I just picked up a75 project myself. I love those year's traded a 81 c10 chevy short box for it but it's missing parts but that's the fun of it lolIm a journeyman heavy duty mechanic so im not afraid of dirt or busted knuckles lol.
I've done a ton of research and know for sure I want a 75 or 76, and all the gremlins they face. Frame and birdcage included.
I have an 05 Harley that I have to give up due to my touchy back.
