I attended a GSA sale last week and purchased a 91 K5 that was wrecked and then stripped (no engine, trans, etc). The frame is bent in the front and in the mid section from the collision but the tub from the doors on back has a few minor dents but is rust free and has two rust free usable doors. I have several older frames (pre 77) that are in very good condition. Has anyone sucessfully mounted a 77-91 body on a pre 77 frame? I realize there would be some fabrication for the middle body mount and that it might require a 2" to 3" body lift to clear the rear passenger floor. Has anyone done this before and is it worth the effort?? Thanks.
