Thanks to MartinSR,s very fine post & photos that he submitted on rebuilding AD hinges I found a method to fab. missing faceplates, hard to find spacers,weld in the sloppy holes and re-center the bushing and pin holes. Would like to share these photos. Sure is great to have this site so we can help each other re-build these fine old trucks.
