Some things to keep in mind. Cab on the truck. Cab off the truck. It matters. Doors on the cab. Doors off the cab. It matters. If you have doors that fit now. Good. If the cab sits on the frame properly, then that is good. Keep as much as you can stable and blocked safely when you repair, patch and cut. When possible I work 1 area at a time. Door hinge pillar is a critical part. Outer cowl repair and inner area in front of the pillar can move the door and hood. Floor repair can shift the cab. The truck is rather simple, but quite precise. Keep stuff aligned and blocked safely. My floor was a mess. I cut and patched a lot. But I kept it on the frame and fixed one mount area at a time. Moved to the inner kick panels and did a lot of cut and fit there as well.The doors were on and off many times to make sure they would still fit.The hood fit well when I got my truck and I never took it off. I had one area where the outside corner of the hood fits to the cowl. and the hood was the only reference I had to work with. Glad I kept it in place. I found some work that was done by the PO. Some good, some bad. If I were to do it again? More attention to the front of the door to the cab. My fit is not great. Slow and careful is my only advice. It would have been nice if the engine had been pulled. But I got around it OK.
