Searched and found a few threads about people thinking about putting a 70 series truck body on a 80 series frame, has anyone been successful in doing this? I did find a thread or two that showed a newish 70 series pick-up body mounted on a 60 series frame done at Proffitt's awhile back. Did they ever do this using an 80 series frame, using the original 1FZFE drivetrain??
