I went to fix the saggy drivers door hinges on my 55 mainline 4 door yesterday.I found the lower"washer" on the himge pin to be non removable! -thats the one with what look like 3 pin spanner holes in it.I finally  got the pins out and bored the holes round in the hinge and turned up a couple of bushings on the lathe.Can anyone tell me what the normal hinge repair procedure is??
