My passenger side door sags on my 55 crown victoria,im not sure how to fix the problem.I thought it needed new pins but where are they located? I know some of you have dealt with this problem so what did you do? 

It sags when opened? You need to have someone pick up on the rear of the door when opened while you observe the hinges. Loose pins are noticeable. Also look for weakness in the hinge pillar and latch pillar or door frame for that matter. The hinge pin holes may be elongated and/or out-of-round,
