I hung my doors the old fashioned way. I picked them up, slid them on the hinges. But before I did that..... When I was doing the body work and test fitting everything before I painted and I had the doors lined up I drilled a few 1/8" holes through the door and the hinge straps. Then inserted cotter pins and removed the bolts. When I was ready I held the door by hand, pulled the pins and slid the door off the hinges. When I installed them I attached a thick blanket to the front of the door jamb to keep the door from sliding into it, picked the door up, slid it on the hinges and put the cotter pins back in. It automatically lines the door back up to where I had originally fit it. Then I put the bolts in.
