I built a budget paint booth inside my dad's metal building. It's basically a stud framed booth with OSB lining and lots of lighting. I have a bunch of furnace filters on one end and a fan out the window. It works pretty well, but I need more CFM on my exhaust because it can get pretty foggy when I do clear. I wet the floor before I start and I open a new Tyvek suit and everything comes out really clean for being a low budget setup.

Re: 1968 GMC - Ol' Blue

Finally got the fuel tank figured out. As I mentioned in a previous post, the Tanks Inc setup is okay, but not nearly as cool and easy as the Boyd tank. This is a 16 gallon universal tank and I had to trim the bottom flange of the passenger side frame rail for it to clear. I also had to assemble the pump and the sender. I ended up using two pieces of unistrut to create a surface for the tank to have something to push up against on the top. I used the straps that came with it and used the same rear hole in the rear crossmember for the unistrut and the strap and then drilled holes in the bottom flange of the front crossmember and used some long bolts. This way I can take it out fairly easy if I need to. I also put some rubber between the straps and the unistrut and the tank.

Fuel system is all plumbed in as well. I mounted the regulator/filter on the front side of the crossmember and routed everything as tight and out of the way as I could. I really struggled with the first couple fittings I put together before I saw a tip to use a heat gun to heat up the end of the hose prior to pushing it on the fitting and that saved me a couple hours of struggle. I knew to oil the fitting and the hose end, but the heat was key. You can buy a $300 tool that puts these ends together, but not worth it for me. I'm taking a gamble on the Russell Twist Lok hose and fittings and hoping not to have any fuel odor. If I do, it's not the end of the world if I have to redo it. I just have to finish plumbing in the fuel tank vent now.

Re: 1968 GMC - Ol' Blue

The biggest achievement of the weekend was the exhaust. I bought a 2.5" builders kit from Summit (natural finish) and used less than half of it. The Summit tubing was thicker than the Speed Engineering downpipes actually. It's a pretty simple routing - a 135 degree bend off the downpipe and then a straight run through the crossmember and into the black widow Venom 250 mufflers. The hangers I bought were intended for a system with more overhead clearance, but I installed them in a cantilever fashion. I left one half of the v-band clamp on the exits of the mufflers so I can finish up the tailpipes once the bed is on.

I used stainless wire on my mig welder with the same Argon/CO2 gas I've been using on mild steel and the welds came out fine. Maybe a little more spatter than with the correct gas, but just fine for exhaust on a driver. I had some silver engine paint leftover so I sprayed the welds for good measure. Also welded in an extra O2 bung for potential future wideband tuning.

My missing wheel cylinder link is supposed to show up today so I can finish up my rear drum rebuild and put the rear end back together tomorrow night. I'm on schedule to set the cab, doors, fenders, and grille this weekend!

Re: 1968 GMC - Ol' Blue

The spray booth you made looked so good I thought you rented one out. Im on the SPI forum now, are there any particular threads you found to be most helpful?

At the pace you're at you'll be driving it soon.

Re: 1968 GMC - Ol' Blue

Thanks haha, it's cheap but it works. There isn't a particular thread to follow, they're each for different types of coatings. You'll see one for clear coat, one for primer, one for sealers, etc. But I spend the most time on primer and clearcoat and restorations. It just depends on what you want to learn about and what kind of questions you have. If you go to SPI's home page, they have a link to "the perfect paint job" which is a good overall approach to a paint job. From there, I dig through the threads and ask questions about specific topics.

And yes, I hope to have it running this winter and complete and driving in the spring.

Re: 1968 GMC - Ol' Blue

The missing link (literally) for my passenger side rear drum finally showed up so I was able to get the rear drum rebuild project wrapped up last night. Weeks ago I started by sandblasting the backing plate, painting it, then the debacle of finding the right brake cables, then the gasket debacle, and finally the wheel cylinder link. I also installed a residual pressure valve to the rear drums.

Yes, I am very motivated. I think I will run the pipes over the axle and out the back behind the tires since I have plenty of tubing and bends left.

Re: 1968 GMC - Ol' Blue

Had a great day Saturday. We set the cab, doors, fenders, inner fenders, and grille. Then we installed the Honda door weatherstripping, dash pad, some sound deadening on the back of the cab, front brake cable, wiper motor, and mocked up the seats. The factory sheet metal comes together quite well and while the body gaps aren't perfect, they were far from perfect from the factory. I was happy that the cab mounts that I picked out ended up putting the cab in the right spot so everything to the front lined up. I only ended up putting one shim on each side for the fenders. To be honest, the front end (specifically the grille/splash shield) went together easier than it came apart. It's so much easier to reassemble a truck when there isn't 10 years between tear down and assembly!

The front end doesn't seem to be any lower than it was prior to cutting 1/2 a coil off. But maybe it will settle a little bit once I start driving it. And I may end up doing a drop spindle one day anyway.

Now onto interior and wiring!

Re: 1968 GMC - Ol' Blue

And for TA, some details on the seats. When I picked up the seats, I took both sides of the connector off the Escalade so I could have a plug and play setup. These seats are power with memory and heat, but I think I can only use the power function because a BCM is required for the heat and memory. No big deal though since I was planning on manual seats initially. I hooked up the big orange and black to a battery and confirmed that all of the movement functions work and to help in test fitting. I saw in sprint's build that he lined up the mounting holes with the front rib of the floor and I did the same thing and it's good reference point. From there, I centered the driver seat on the steering column and there is plenty of room for adjustment and a great amount of legroom. I haven't decided what I want to do for a console yet. We put the same vintage seats in my dad's 64 with a 08-13 center folding console (since they're much less creaky than the 99-06 folding consoles) but I'm not sure that I have enough width between the seats for it. I may end up building something anyway because I need to mount by bulky Gen 3 PCM and TAC module down there. I had the passenger seat all the way to the edge of the rib and I might be an inch or two short of being able to install a 08-13 console.

I forgot to take a picture with them in place.

Thanks guys. I'll post a picture when I have the seats installed, but it will be a couple months probably. Don't want the seats in the way before I'm done with the interior. I would roll it outside for a good picture in the sun, but it would be hard to push it back in.

Re: 1968 GMC - Ol' Blue

Today I was waiting at a stoplight and a Voodoo Blue Tundra pulled along side me, I was crowing my neck to get a good look at it. I was thinking how good your truck must look in person. These pictures you just posted confirm it!

Thanks man. I'm pretty happy with it and can't wait until I have all the parts in blue and out in the sun.

Re: 1968 GMC - Ol' Blue

I got a few small things done this weekend.

I got the LS harness through the transmission tunnel which was a challenge but I got it done.

My carpet showed up, but was for a low tunnel as I suspected it would be so I have to return that and get the right one.

I also set the wiring fuse panel and wired up most of the main power in the engine bay. I used bolts to attach to the firewall instead of the supplied fasteners (basically wood screws) for a more solid attachment.

I also got the hydroboost and lines mocked up. I have a couple of the lines at NAPA right now to be modified to work. I made a new backing plate to attach the hydroboost to the firewall. I cut the clevis off the hydroboost pushrod and cut the OEM pushrod off at the threads and it should give me a good adjustment range. I've seen guys thread one pushrod or the other, but it was a lot easier to just cut the ends off both pushrods and weld the two together.

Re: 1968 GMC - Ol' Blue

Oh hydraboost.... How I wish I had thee.... Your setup is going to be much cleaner with that setup. I like how you welded the rod like that. I will remember that when I eventually convert to hydraboost.

I like seeing your bulkhead connection, it looks so clean. You bought the full OEM c10 harness from American Autowire right? I am still contemplating my move on this. I am thinking about keeping my cheaper wire harness(AA), sanding down and welding in a patch for the square bulkhead hole, and trying my hand at painting/blending... But this is a lot of work and it will mess up my lizard skin on the inner firewall a little bit.... Ugh. But now seeing your firewall, I feel like spending the extra $300 just to make it easier on me...

And it never gets old seeing that blue man Keep up the good work!

Thanks man.

I bought the Classic Update kit from them. So it has a few circuits for modern updates like power seats, power windows, power locks, and a couple others. I don't know what your harness is like, but having a harness made for your truck is easier for sure. How much easier? I don't know. But the classic update kit has a really nice main power harness and everything is about the right length or too long, so you don't end up short anywhere. It also has the correct connectors for things like the steering column, wiper motor, instrument cluster, lighting, etc.

The kit was $539, but prices may have just gone up. Have you already opened yours or is it eligible for return?

Re: 1968 GMC - Ol' Blue

It's eligible for return which is why I was thinking about the classic kit. But mine was only $300 ish and it has all the same connections yours has for GM stuff like dash and steering column but it stops at fuse panel on inside firewall. You have to run the engine bay wires your own custom way. Which would have been fine if I had thought about that and shaved the big hole to begin with.... This thing is nickel and diming me to death though so I'm probably gonna end up closing the hole and running the wires out the cowl or something...

Edit:. Does your kit have the OEM connector for windshield wiper and washer connectors?

Re: 1968 GMC - Ol' Blue

It does have those connectors.. I know what you mean about the nickel and diming. What I've learned is that you can pay a little more and save a lot of trouble. Making something universal work takes more time and may not yield the best result. Avoiding replacing something due to cost won't be any easier down the road when things are together. Just my lessons learned. Many more to come I'm sure haha.

Re: 1968 GMC - Ol' Blue

Thats a nice upgrade to the bulkhead bolts. I remember that being an area I wasnt overly impressed with on mine.

Re: 1968 GMC - Ol' Blue

Did you use some kind of grommet where the wires come through the hump?

I want to do the same thing. I'm behind you and TA. I have Most of the metalwork done to my cab. Still need to weld on the rockers. I had to do outer floors, cab corners, cab supports, etc...It was 8 patch panels per side. With a sprinkling of other patches on the floor. My floor also had most of the welds broken at the front like yours. I say now...it would have been easier to do a whole floor, but much more money.

Re: 1968 GMC - Ol' Blue

I have one, just haven't installed it yet. My engine came with the harness that goes from the TAC module to the gas pedal and it had a grommet on it which was huge for such a small bundle of wire. So I cut the middle out of it and also cut it in one spot so I could get it in place after pulling the wires through the hump. It turned out to be the perfect diameter after cutting the middle out.

And yes, if the floor was cheaper, I may have gone for it. The only mistake I made was not paying close enough attention in mocking up my driver side outer rocker. The inner floor section ended up further outboard than it should have, so the inner lip of the outer rocker and that ridge in the outer floor come pretty close and it made it hard to install weatherstrip and I'll probably have to trim the sill plate to make it lay down. Hopefully yours came out better than mine!
