UPDATE on saggy front doors.
During my search for hinge pins/hinges I ordered a new hinge which arrived very late and is now surplus to my needs.
Willing to sell it at a loss, to someone on here, just to recover some of my cost. Otherwise it goes on Ebay.
Genuine Nissan part (not junk from China). I paid $60.13 including shipping which I believe was about $13.00.
So, about $47.00 before shipping. Would take somewhere in the thirties plus shipping. Would ship from 27530.
Reasonable offers encouraged!
