So I recently picked up a short bed 76' Dodge D150 truck that I was going to swap parts on and resell but found that nobody wants a slant six, 3 speed manual 'smog truck' truck in California so I may end up parting it out. I was wondering if any mopar trucks from the 1930's-1960's would fit on this frame. Drivetrain runs fine, has disc brakes, 8 1/4 rearend, frame mounted gas tank, not a speck of rust and even as 4.5 five lug bolt pattern. I have a few friends with early trucks so I could just give it to them to use instead of sending it to the crusher. If it would fit what mods would be needed?
