I have a project in mind and need some advice. i picked up a 1973 3/4 (454)ton crew cab last year and put a new flat bed on it. i got a 1973 1/2 (350)longbed, which was my grandmothers, and a got a 1991 3/4 (350)4x4 suburban for $250 last week. I would like to start a crew cab 4x4 short bed project, but trying to figure out which frame to start on. i am open to any suggestions. thanks.
