Not sure if you have to remove the fender to remove the hinges, but it should only be 2 bolts per hinge on the door side that will let you get the door off the truck. Then you should be able to get to any more bolts that will be holding the hinges on. I would not trust the old hinges on the truck the door is being replaced, get either new hinges or get the ones from the donor truck. When replacing the door install the new hinges on your truck first then with the help of a friend install the door to the hinges. DO not tighten the bolts all the way until you have everything lined up. Once everything is lined up then you can tighten the bolts all the way. It will take a bit of trial and error to get things right. Best way to do the door is to remove the fender close the door, then line the door up with the frame and the rear of the door, and last the locking mechanism. Then replace the fender and line it to the new door and the hood. Take your time and be patient rushing will only cause problems.
