"Sin-thia" My 74 GMC
 
I have actually started working on one of my projects so figure it's time to start a build thread.

I started with a 74 GMC long fleet with a 350 2bbl 3spd on the column and a dump setup on it in late '08......

My dad, uncle and I began removing the rusty beat up bed and dump setup......

Well I hadn't done much to it except pull the engine and trans until just recently when I finally cut the frame down to turn it into a short bed. I started measuring for my cuts and making my marks, I started at 8" behind the cab mount crossmember......

Then from there I went 14" back and started laying out all my lines......
http://i164.photobucket.com/albums/u...C/IMG_9398.jpg
http://i164.photobucket.com/albums/u...C/IMG_9400.jpg

I started to use a sawzall to make my cuts, but I used 2 blades within about 4" of cutting (most of been really cheap blades, they were a gift). So I brought out the torch, it was alot faster anyway......

The point of no return......:lol:

And after what seemed like several hours of grinding, due to only have an air grinder and having to wait on my 30gal. compressor to constantly rebuild pressure I was ready to start reassembly......

Re: "Sin-thia" My 74 GMC
 
So I clamped it together and measured for squareness and I think I only had to slightly adjust one side once, then tacked and remeasured a few more times......
http://i164.photobucket.com/albums/u...C/IMG_9592.jpg
http://i164.photobucket.com/albums/u...C/IMG_9593.jpg

I used part of the sections I removed to make plates to reinforce the joined area, they are offset as well. Where they ended up under the bed bolt holes, I just test fit them in there and took my silver sharpie and traced the hole. Center punched it and drilled it out slightly larger than the bed bolt hole is above it with a uni bit. (sorry I didn't think to get any pics of that until they were already welded in)......
http://i164.photobucket.com/albums/u...C/IMG_9594.jpg
http://i164.photobucket.com/albums/u...C/IMG_9595.jpg

Then I was able to start welding it up. You can see the inner plate through the bed bolt hole......

Re: "Sin-thia" My 74 GMC
 
Then with the help of a friend, we sat the bed on to see if it all turned out ok. (sorry about the "sky shot", but my driveway is extremely narrow so I had to shoot the pic from my backporch)......
http://i164.photobucket.com/albums/u...C/IMG_9599.jpg

And we test fit 2 of my dodge 20" steelies to see how they would look on there......
http://i164.photobucket.com/albums/u...C/IMG_9601.jpg
http://i164.photobucket.com/albums/u...C/IMG_9600.jpg

I have had alot of ?s about the center cap. :devil: It is indeed a rally cap, and it is held in place by the factory 3 bolts. I will try and get some pics of what I did to make them work on there soon. It's real easy and just takes a little time, I think I have about 30mins in this one and only 3 more to do.

Next up on the to do list is a 2" Z, 1.5" chopped crossmember (maybe raised into the frame another 1/2"), 3" drop spindles and then to flip the rearend on top of the springs. May take some time, because I want to geat all new bushings and balljoints and what have you as I do that and i'm broke.

if u ever decide to get ride of them let me knw

Re: "Sin-thia" My 74 GMC
 
Right on!

It's to bad the GMC's get no love from the aftermarket and it's not likely that these grilles will get reproduced. Hell I have a really nice 73-74 chevy grill and a see dozens of them on the road in beat up trucks around here all the time, but i've only seen one other GMC grill in person and it appeared to be better than mine is.

I love the dodge steelies...I just don't like the idea of using adapters...they look awesome, though!

Thanks. Yeah, i'm to sure about them myself but these wheels are temporary until I can afford the ones I really want to get, which may be awhile because they aren't what you would call cheap.

That's awesome! You always see and read about guys going from GMC to Chevy, nice to see it going the opposite way for a change. Not that I don't like Chevy's.

That's a great job on the frame. Nice welds, too.

Thanks
I need to work on it some more but it's been rainning here quite a bit here the last few days and I only have a crowded one car garage so I can't get much done unless the weather is right. I am supposed to go pick up a tach cluster tomorrow night.

Re: "Sin-thia" My 74 GMC
 
Wow! I didn't realize that it had been almost a month since I had updated this, but I have gotten a little bit done in the last few weeks.......

Got the rest of the front clip removed
http://i164.photobucket.com/albums/u...4%20GMC/Zl.jpg

Did my Z, 2" up + 1" forward......

I plan to clean it up so it all flows smoothly before I paint or powdercoat my frame.

Crappy cellphone pics

Re: "Sin-thia" My 74 GMC
 
Had a nice day today so I did some more work......

I put the front wheels back on for a short bit and put a fender on with just 2 bolts to see what it looked like....
http://i164.photobucket.com/albums/u...20GMC/Test.jpg

And then I took them back off and removed the crossmember so I could get a 1.5" chopped one put in......

And where I stopped today....
http://i164.photobucket.com/albums/u...rossmember.jpg

I still need to Z my frame horns, but i'll get to that soon.
