It can be done, me and a buddy of mine did it to his 90 model. We had a complete barndoor truck to rob parts off of. Made it alot easier. You will have to cut the mounting pieces for the hinges out and put them on your truck. You will have to cut the latch out at the top and weld it on yours and finally you will have to change the bottom sill. We used a spot weld drill bit to remove it from the donor truck. It is a good bit of work but worth it IMO. If you can weld and measure you can do it. I would recomend getting a whole donor truck, it made it ALOT easier. E-mail me if you have any ?????.
