My question is this, I have an 80 chev 1/2 ton, fleetside longbox, good power train, body not so good, been looking for some time now but no find on a a good 48 to 58 gmc body to put on the frame, run across a 56 **** , a 1/2 ton shortbox would this work? what mods are involved? I've seen how chevy frames and so forth under a **** Body in magazine articles. Anybody knows anything or do's and don'ts, let me know would appreiate the help and comments. Thank you.
