I have a '86 crew cab and would like to mount it on a '96 chassis. Or swap the 7.3 into the 86 and get rid of the 6.9. What do you folks think would be the easiest? The '86 is a single wheel 4x4. I would like to keep that. The '96 is a 2x4 dually. Would it be feasible make the '96 a 4x4. Or have I lost my mind? LOL

Thanks!
Gary
