89-92' might work but I KNOW an 86' will not. all the measurements were WAY off and almost everything was different sizes. And yes i think at 92' would work!
The cab actually pounded out really good, just removed the roof liner and used a lift jack and she lookes pretty decent, good enough to haul wood! Got the door bended back into shape and htey even close nicely. Just need to weld up the supports and put in the new windshield.
