I just got a couple of rigs (same body style) and one of them has the cab in really bad shape (an 81 F-350). The interior has had mice in it the metal is rotted and rusted everywhere and is bent up pretty bad. The other is in top notch condition, excelent interior, perfect body, no problems(an 84 F-150). I need the F-350 for work as it has the load capacity I need. The F-150 could be just for playing or a daily driver. Is there any legal issues that i will have to worry about swaping the good cab onto the other frame? Im not on here to often but any help would be much apreciated. If its just a swap over type job than I know a guy who has a good spare 87 ranger cab (the frame is twisted and bent badly) that i could convert to the F-150 frame.Thanks a million in advance.
