The driver's side door on my 98 Mustang is sagging. I'm trying to decide if I should try and put replacement pins and bushings in or buy replacement hinges from Ford. The hinges looked to be bolted on and not welded. Any suggestions? Looks like it will be a straight forward repair / replace but I'm bad about under estimating what it will take. Ford Service Center quoted the upper hinge at $49 +/- and the lower hinge at $ 70 something.
