Gorey's 67 GMC 3/4 ton Shop Truck
 

Alright,
Here is the start of my thread for the 67 GMC 3/4 ton I just purchased 2 weeks ago. It was purchased new in Arizona, and was used as the shop truck for decades. Recently the gentleman gave the truck to his nephew who served in afghanistan as a gift, and it was trailered back to indiana.


I posted a gallery and will work to keep it updated when I work on the truck.

http://67-72chevytrucks.com/gallery/...7_gmc_left.jpg



I found it on Craigslist and I had been looking for a couple weeks.

It is in excellent condition for how old it is.
There is only 1 through body rust spot on the whole truck and that is in the driver side rocker panel.

http://67-72chevytrucks.com/gallery/...ocker_rust.jpg

Other than that it is all surface rust, and there is one dent in the whole truck.
http://67-72chevytrucks.com/gallery/...der_damage.jpg

Prior to buying it I had already made plans to purchase a 66 or 67 GMC and pulling the v6 and trans that is had in it and replacing with a 350, so it coming with one only made my job easier.
It has a 350 with a 4 barrel holley carb and a 400 turbo trany.
The carbs need to rebuilt and I purchased holley brand rebuild kit, New floats, and choke linkage kit (the linkage was trashed) and have all the parts to do that now. Even so, the engine runs good.
Just replaced the plugs, but probably need to go ahead and replace the plug wires, distributor, and rotor, Will be also replacing the belts asap, as will the thermostat gasket. It is leaking.

http://67-72chevytrucks.com/gallery/...humbs/3501.jpg

It has a very recently rebuilt rearend
http://67-72chevytrucks.com/gallery/...lt_rearend.jpg

currently it has no rear brakes. You can see the last owner put a pair of vice grips on the brake hose in the rearend pic. LOL
I also have all the parts to rebuild the rear brakes soon. And will also need to reattach the emergency brake.

The truck has some great details to it

http://67-72chevytrucks.com/gallery/...ood_detail.jpg

So what I was thinking of doing is cleaning up all the rust, and doing a faux finish patina paint job. So it looks old, and distressed, but is protected. I have alot of experience in doing this in my business. I haven't done any painting on trucks but tons and tons of Haunted House props since that is my business for the last 13 years.

It also used to be a camper as evidenced by the tank switches, and the left and right fuel tank covers that do not have tanks behind them anymore
http://67-72chevytrucks.com/gallery/...k_switches.jpg
http://67-72chevytrucks.com/gallery/...l_tank_lid.jpg

I also just purchased baby moon hub caps and 16" trim rings from
http://www.autoamenity.com/
I was surprised to find 12" baby moons to replace the ford dog dish hub caps that came on it. I looked for days. This was the ONLY place I could find 12" baby moons let alone being 2.5 inches deep.
http://67-72chevytrucks.com/gallery/...bs/hubcaps.jpg
I will be selling the ford hub caps as soon as I get the new hubcaps on it.


I know that most hubcaps do not fit over the floating hubs on the heavy duty rearend. But I measured and these are REAL close. The Baby moons I found are 2.5 inches deep so that should be enough to drill out and tap screws into the rims if they do not snap onto the 4 humps on the rims well enough. I will also be painting the rims to match the body.

The interior, dash, and gauge cluster are also trashed.
http://67-72chevytrucks.com/gallery/...interior15.jpg
http://67-72chevytrucks.com/gallery/...ge_cluster.jpg

And lots of other misc broken parts like the driver side mirror, vent window glass, and handle, and shifter knob. The windows seals ALL seam to leak. And ALL the body and bed mounts need to be replaced.
But I know I made a great investment. The important parts such as the frame, engine, transmission, rearend, and body are ALL in phenomenal shape.

It also came with ALL the trim work. Some is slightly bent so I possibly be selling it to.

Please comment,
I look forward to learning from the members of this forum and hopefully I can impart some of the little knowledge I also have to this group.

:hi2: and :welcome2: to the site goregalore!!!:lol: love that user name!!!:metal:

Looks like ya picked up a good truck....those buddy bucket seats are a rare item, so although they are abit over used, I would tell ya to keep and re-upholstery them....the dash bezel is an easy replacement item too....post up a pic of the inside of the glovebox door (SPID)...love to see what other options it has:D

Good luck with your build and ask those questions...we are here to help!!!

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

this ought to be interesting!

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

thanks gcburdic
Gore Galore is my business so, sorry to say I am not being that inventive;)

Here is a bit better shot of the dash and glove box. It is in good shape, the glove box that is.
http://67-72chevytrucks.com/gallery/...umbs/dash4.jpg
The seat foam is also in good shape, but I need to do the window seals before I try to recover the seats. I can see it degrading the foam now. I have seen aqua vinyl online, but I think a tweed or other breathable material more comfortable.
Do you know of a good source for the dash and the seat covers?

litew8, I really do hope it will be interesting. I want to get the truck in good operation, then I will play with the patinas. I gave the whole truck a good cleaning with my power washer. I still can't believe there is not one hole in the bed.
And the gate is straight.
http://67-72chevytrucks.com/gallery/...humbs/bed6.jpg

Oh, and something else interesting. I have the stock underdash air conditioner. The original owner took it out soon after buying it, so it has been in a box for over 40 years, and so it should be in good working order, Supposedly.

And I have the original GMC owner's and drivers manual, and Protect-O-plate still in the owner protection plan manual from the issuing Buick Dealer. Oh, and there is a picture of the original owner in the manual. LOL

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

This is looking to be a great inspiration for the paint I am looking to do, plus more faux rust.

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

Have you done your homework on where they tend to rust most? Guess you wouldn't have to look far for examples. :lol:

thanks again Gents.

Here are the glovebox pics you requested.

http://67-72chevytrucks.com/gallery/.../glovebox1.jpg
http://67-72chevytrucks.com/gallery/...e_glovebox.jpg


I also already received the baby moons I ordered. And I am happy to say, Easy fit. 12" Baby moons that are 2.5" deep fit just fine over the floating hub rearend. I am waiting on the trim rings to arrive.

http://67-72chevytrucks.com/gallery/.../gmc_moons.jpg

But I am very sad to say I talked to Hubcap mike when researching the purchase of the hubcaps, and trim rings. Rather a jerk that acted like my business was not worth messing with.


Here are more pics of the patina on the truck that I want to expand upon.

http://67-72chevytrucks.com/gallery/...ina_fender.jpg

And there are a couple spots of paint that have crackled. I can also do this effect. But not sure how this would be seen. It would be labor intensive. Just not sure if it would be worth the work.
http://67-72chevytrucks.com/gallery/.../crackle_2.jpg

And here is the logo I will be doing on the doors but either in white or black. And then distressing or white washing to age the look.

Glad you can appreciate the humor in it, and it is going to look good too.

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

Today I put on a new thermostat gasket. The old one was leaking. I tried to put on new fan belts but the new one was just short enough to not work, and the next size up was not in stock so stalled out.


But having been reading the boards and hearing about using molasses and water as a rust remover, I had to try it.

I started a gallery for this project. Will post more pics when complete.

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

Finally got both belts replaced. Now it doesn't whine when Accelerating. those belts were frayed and nasty.

Okay,
I am having some frustration with getting my rear drums turned. I have been wanting to get the ALL new rear brake parts installed, but took the drums to several shops and each said the size of the hub (4 9/16) is too large to put on the lathe.
So need to mount on the hub to turn.
I was hoping I didn't need to pull the hub but realize i need to anway to do the brakes. Duh! So, I will look at doing that tomorrow after work. I think I will just need to replace the seals when I pull the hubs.

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

Never had drums turned before. Interesting.

Holley Carb rebuild
 

I really could use some input here.

I just started cleaning and rebuilding what I thought was a Holley 4160 carb, but I am not sure what it is now. It says 6R-7809, and on the horn 1950-5 and 2410 under that. I crossed check the #s and came up with part # 80457 which is a 4160. But I could be wrong.

I thought 4160 had an electric choke, but this one does not, or atleast it doesn't now.
The choke linkage is trash. It has a hand made choke arm, plus someone has ground off a part of the linkage. I have all the linkage parts except the choke arm in the rebuild kit.

I purchased a holley trick rebuild kit, the choke linkage kit, new floats, and a new secondary diaphragm.

Other possible issues.
I am going to replace the floats but I was also trying to determine why this carb was loading up on fuel.
I noticed one of the floats is newer than the other. And they were different weights. You could tell just by holding them, but they were also labeled (primary) F4 and (secondary) F80. To be honest, I don't know what that means.
Plus the float springs are obviously different they look different and have different compression strength.
The primary float is lighter as is its float spring.
The secondary is the heavier float as is its float spring.

So, I guess I will finish cleaning up the carbs, and after talking to a friend about the floats and possibly getting a new linkage then reassembling this thing.

Turning drums or buying new
 

I have been working to get the breaks rebuilt on this beast, I was able to determine that I would need to buy a new hub just to get the drums turned so I think I will be out about $75 in the process with the turning cost, plus the cost of getting a hub to use to turn them. Which has turned out to be a pain in the arse. And I don't know how much life is left in these drums.

But I did price premium drums and they were $49.99 a piece including shipping through napa, pre-discount. So, maybe $40 a piece for brand new drums.
I think that is a better option all around so they have been ordered.

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

any progress?

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

Yes, actually
Got the Carb rebuilt and cleaned up and put back on the 350. It doesn't load up anymore. Thanks to prostreetC-10 for donating and sending me the choke arm to complete the rebuild.

It took me 2 full days to do the cleanup and rebuild, while my wife was gone so I could use the kitchen table, using the Holley trickit kit, the manual choke kit, and new floats. but it runs SMOOOOOTH!
It took it over to a mechanic friend and he said it was as smooth as it could ever get.

I just need to check the needle valves and floats for the last time and call that part done.

As soon as I get the chance I will post the rebuild pics to a new gallery. I figure it has to help some newbies such as myself.

My business is crazy busy right now and time if of the essence.
http://67-72chevytrucks.com/gallery/...build_done.jpg

And the choke cable seems to be too long. It isn't pulling the choke butterfly as smoothly as it should. So, I will need to trim the cable down some.

Next step is to install all the new brake components. But have had alot of trouble figuring out all I need for the emergency brake install. I don't want to install the brakes and then tear the brakes back apart to put the e-brake on.
Cables have been ordered. But not sure than is going to be enough. I have e-brake cables running to the back side of the cab on both sides, but ends there.

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

Recommended Vendors,

I am seriously interested in some recommendations on suppliers.

I need

-Dash pad
-new gauge bezel with gauges. ALL the prices seem to work out the same when you add the gauges in or without when you add all the costs up.
-weatherstripping (windshield, doors, etc...)
-rear blade bumper (I would prefer OEM and I will get it chromed if necessary.
-seat covers. My wife and I can probably make them ourselves using my shop industrial sewing machine. But it would probably cost me more if we do.


I made a purchase from Brothers.
I got the parts in quick fashion. All I ordered was the urethane cab mount kit. It looks like a good kit, but no instructions for install. And of course this kit looks nothing like what the oem mounts look like.
I also purchased the factory assembly manual.
Very cool but also very confusing.
It has no index and the only organizational part is the trucks are broken up into model. But I purchased it for the purpose of looking up the Emergency cable installation. And guess what? I can't find it.

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

Nice to see another gmc like mine on here!!! I'll be watching!!!!

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

Hey gore....

There are several board vendors that can take care of your needs here...GMCPaul's, Top Banana, Classic Heartbeat, etc....

The factory assembly manual is quite confusing, but get your self some colored post-it notes, and page through it writing down info on certain pages and color code them for specific items (ie. interior, engine, etc)

Here's my favorite pic of the ebrake setup....hope it helps ya:D

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

Thanks Craig,

I really appreciate the info Geoff.
The image really helps. I ordered the read brake cables but I wonder if the clips will come with them. I have seen the cable run, but this image is perfect. But the one thing I am still having trouble finding is the hookup through or to the drum itself.
I can't seem to find any pics of this.
When I bought this truck it had NO rear brakes. The drums weren't even on it. So I have no idea what it is supposed to look like. But almost there!

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

Check the parts board for guys parting trucks....if the ebrake is still there, they should be able to retrieve the hardware necessary for it to go back together....as for the cable connection to the drum brake itself, try this...http://67-72chevytrucks.com/vboard/s...ad.php?t=94977

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

It took me quite some time just to find All the E brake parts I needed to put them back on this truck. thanks again to the members of this forum to help me find the answer.
I ordered the parts from Napa. But they were wrong.
SO, I chose wwwinlinetube.com for the rear Oem e brake cables, clips, and clamps but in stainless. I went ahead and ordered all new brake lines and drop hoses too since the ones on the truck were looking pretty rough. I am pretty much doing a complete brake system overhaul anyway so I might as well do it right.
I will be taking some pics along the way. Hopefully I will start on this next weekend.

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

Wouldn't you know how it always goes. I got all new brake spring kit, wheel cylinders, etc... The Napa parts are working fine, but they do not work with the stock parts I had on hand so I had to also buy new brake bars. I also didn't realize the wheel cylinders did not come with the push pins, or push rods. So, I have the truck on jack stands with the brakes built minus push pins.
And I CANNOT find any anywhere. I have called LMC, the truck shop, and also all the local salvage yards.
So, Now I need to call on some members of this forum to help me out.
Anybody have 4 wheel cylinder push rods for a 67 gmc c2500 with leaf springs, 2.5" brakes shoes, and 12" ID drums.
thanks

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

Alright, I just partially finished the install of the brake lines I just purchased from www.inlinetube.com. All I can say if this was the perfect solution.
I just cut the old lines out to make it quicker to remove couplers and T fittings. Clean the fittings and started matching up brake lines.
So easy when you buy pre-bent lines.
I also wire brushed the master brake cylinder, and the booster. And applied rust converter. It looks alot sharper. I will post pics tomorrow when I have light to photograph by.

And Duane (Heavymetalchevy) is sending me 2 wheel cylinders w Push rods.
Hopefully this will solve my last parts problem for the brakes.

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

Tell your experience here where they are discussing pre-bent brake lines.

GG, the truck won't be finished for Halloween!! :( lol
Good to hear things are getting better though.

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

That would have been nice, but slow progress is always better than NO progress.
I responded on the thread as your posted.

I just need to build a garage now so I can tear this truck apart and do to it what it deserves.
I ordered door seals, and got my windshield setup for getting new seals in. I am getting more rust in floor pan than I would like and the driver seat is getting wet.
So, solve those problems and then it might be time to finish the inside of the cab.

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

I agree, some progress is better than none.
Consider a (cheap) tarp for the days you cannot work on it.
In the meantime, also maybe consider spraying something on the floor to keep the moisture off.

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

Here is a pic of the master cylinder, booster, and lines before cleaning and installation of the stainless steel brake lines

http://67-72chevytrucks.com/gallery/...ter_before.jpg

Here is what it looks like now with some wire brushing, rust converter, and installing new lines.

http://67-72chevytrucks.com/gallery/...ster_after.jpg

well, in regards to installing the inline tube lines. I had no trouble, and everything fit perfect until I reached the rear drop line. I had to put an almost 90 degree bend for a downward turn to install into the drop line mounting plate. And I had 2 other problems. The T fitting is too small of a fitting for the left and right lines. And the line to the Driver side wheel cylinder seems too long. It will fit with a little squeezing. But it doesn't contour the rear end the way I think it should.

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

Well, I had to buy a new brass T fitting, but that is ALL I had to do to make ALL the brake lines come together perfectly. Like I said before I had to do a little squeezing but everything fits really tight and it looks great.

I will have to say I have been having a hell of a time with the brakes. The new parts do not look the same as the old parts, and I am having real problems with the brake bar springs. I think I am right about this. But you have to bend the springs so they fit around the end of the brake bar. But when I try to bend the springs they do not bend the same all around. I know I don't know what I am doing. But because of this one problem. My truck has been sitting here close to a month with the truck on jack stands. And the read brakes just covered with plastic bags. I would love some feedback on this.
I need this done soon. I have a guy ready to take out my windshield and put a new seal in before winter to avoid anymore water getting into the cab.

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

Hey gore...did a quick search using the search feature above and found this thread for you that contains a link to a great write-up for those darn brakes....hope this helps ya and you get that truck rolling again:D
http://67-72chevytrucks.com/vboard/s...d.php?t=497055

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

All I have to say is thank you to the gentleman that created that webpage. Without that I don't I could have done any of it.
That is exactly what I used to get where I am. The only thing I have left is the brake bar spring. and the problem was finding the item # for it. But I found it on another thread and just ordered it about 10 minutes ago. I have been looking for that for quite some time. But hopefully on Monday I can get it back together.
What a great project. I just need a garage to put it in now. ;)

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

How's goregalore coming along?

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

Put a new windshield seal in retaining the chrome.

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

Things are underway again. I ordered a new brake booster and master cylinder. Yup, the brake booster is going out. All I will have to do is replace the front wheel cylinders or rebuild them and new pads, and it will have 100% brand new brake system. I wasn't wanting to do all this. But this is how it is.
And the power steering is going out. So, will have to do that too pretty quickly.

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

If you have that garbage ram-assist power steering, waste not another nickel on it. Keep dumping fluid in it, and then put a 73-up power box on it. MUCH better, and an esay swap. Should be plenty of info on here about that swap. Cool old truck!

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

How can you tell it is the Ram assist?

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

I was wrong about bending the springs. The brake bar springs do not come with the drum kit. You have to also buy them separately.
From Napa, I had to buy:
For the rear:
-the new drums (cheaper than having them turned due to being 12" for the 3/4 ton)
-wheel cylinders (they do NOT come with push rods)
-push rods (which you cannot buy new, I had to buy from a forum member)
-brake pads
-brake drum kit
-brake bars
-brake bar springs
-then the complete stainless steel lines
-brake booster
-and went ahead and picked up the master cylinder since it was only $20.
-will need complete ebrake system (i tried just new rear cables but the rest are so stretched it doesn't work)

But even without the new brake booster it works. Just sometimes the peddle gets really hard and doesn't give all the brake it should. and with the vacuum seal leak the engine revs when you press the brakes and makes it hard to shift into gear.

Re: Gorey's 67 GMC 3/4 ton Shop Truck
 

Interested in your build.
