70 gmc DIY build
5 Attachment(s)
Been around the forum for 20 years now (time really flies) but this will be my first official build thread. I bought this 70 gmc custom from the original owners daughter. It was sold in and spent it's life in clarmore oklahoma where I lived as a kid so I probably saw it driving around at some point. Truck came with the protect o plate and tons of paperwork going back to 1970 including for the crate 350 with 22k miles on it.
Here it is as we brought it home a little over a year ago |

Way nice!!!
Can't wait to see more pictures, and info, and work done!!! I'm not knocking the bug deflector, but those cost you about 2 MPG going down the highway...yes, it's really THAT bad.. |

My dad and I put on new belts hoses radiator an hei and I rebuilt the quadrajet. Took it on it's first drive in 5 years. Old man camper shell ford hubcaps and all. Then I ditched the camper shell and put on some new tires. Changed a few bulbs and it was road worthy.

Re: 70 gmc DIY build
That is a nice truck. Not only is it in great condition, but it's well optioned.
Clean it up a little bit, check the brakes, running gear, tune it up, and drive it! |

Had been looking for a set of dog dish caps but lucked into some full wheel covers and an extra set of centers on ebay for a steal. Not perfect but matches the condition of the truck nicely. Was originally optioned with full covers anyway.

That's the nicest original blue steering wheel I've ever seen. I'll be looking forward to your posts!

One of the very few non original things on the truck was the seat that was out of a squarebody and very uncomfortable. I found a full foam bottom seat for cheap but the guys dog had gotten a hold of it. With the cost of new foam I decided to try something different picked up some foam thick enough to cut out the chewed out areas. Cut out the areas then glued in the new foam. Turned out pretty good and cost less than $25.

Does the new foam feel the same as the original? |
Re: 70 gmc DIY build
Definitely curious on the seat foam as well. I'm in for the ride
|
Re: 70 gmc DIY build
Very cool seat repair, not sure if I have seen that type of fix before.
|
Re: 70 gmc DIY build
The foam isn't quite as dense as the seat foam but its the closest I could find in the thickness I needed. It was pretty simple marked my depth on a sharp knife cut strips front to back then went in perpendicular to the seat and cut them out. smoothed it out with a flap disc then glued in the new foam and dressed the edges with the flap disc to match the rest of the seat. DO THE SANDING OUTDOORS and compressed air is helpful to clean off afterwards because you'll be covered in bits of foam. I basically did this as a temporary measure till I get the seat recovered. Just has a saddle blanket cover on it now.

I decided to see how well the faded paint would buff out and was pleasantly surprised. Night and day difference. Couple pictures next to my panel afterwards.

The truck ran fine with the stock q jet but if you let ie sit over night or even all day at work you had to crank and crank on it to start it. So I decided it was time for a tried and true holley and edelbrock intake swap. Did the valve covers too. Was pleasantly surprised at the added power.

Drove the truck like that for a while just fixing minor things on it till April of this year when things got interesting. If you're one of those save the long beds guys look away now.
I bought this truck with the intention of cutting it down. After a lot of research I had put a plan together and it came out pretty good for my first time. Disassembly is pretty straightforward except for having to drill out all the carriage bolts because the heads just spin. Found a little rust under one of the wheel tubs. I'm guessing it was caused by fuel tank#4 in the bed. Since I'm working alone I figured cutting the floor on the frame would make it easier to move. I didn't splice the floor but more on that later. |
Re: 70 gmc DIY build
Decent looking truck. Snip away!

Measured multiple times and made templates so my cuts would be as exact as possible. But on the passenger side I had to put a jog in my cut to remove both the fuel door and filler hole for the in bed tank. I placed the horizontal cut so that it would be underneath the trim.

Re: 70 gmc DIY build
Great project.
Keep up the good work. |

So after the lay out and lots of double checking it was time to cut. I cut the outside skin first then marked the inner skin off of the cuts through the top rail. Ended up with this.

Re: 70 gmc DIY build
Looks great! Nice job!

Re: 70 gmc DIY build
Getting dizzy just staring @ the puzzle pieces :lol:

Re: 70 gmc DIY build
Absolutely the cleanest cut lines I've ever seen... How in the world did you maintain such accuracy? Cut off wheel? The sanded edges look to be a consistent 1/4"... I'm curious how you did it.

Re: 70 gmc DIY build
Looks great! Nice work.

After getting things cut apart and cleaned up it was time to stick them back together. Using .023 wire with 75/25 shielding gas.

After they were welded up. I took my time and skipped around but there was still a slight amount of warping. Probably impossible to have zero warping without body work.

Re: 70 gmc DIY build
Looks great to me!
