A built a 56 years ago. Started with a 59 gmc frame. Used the front frame clip from a 80 gmc. Grafted it onto the 59 frame right in front of the front cab mount. The frames are almost identical. Same shape but about 1/4 inch shorter in height. Matched them up in a ‘z’ shape and welded them up.
That way I got a better front set up including the power steering and brakes. I mounted the booster on the firewall. Even used the junction block and wiring harness. Used the rearend from the 80 too. Slight massage to the dowel holes on the spring pads and it set right in place.
Popped in a 350 and turbo 350 and off to the races.
Got it wired and the original heater working and the new owner left on Christmas Eve in the dark with poorly aimed headlights. It was 20 below. He drove it 700 miles home in 4 days. He was a braver man than I am doing that.
Sorry for the long story!
I did consider a Camaro sub frame or mustang 2 conversion but the 80 gmc was acquired in a trade for a 72 nova. I had 3 grand in the truck when I sold it.
If you’re really bucks up you can even buy a complete custom chassis ready for your cab and box.
Lots more choices these days.
