my hinges:
http://s67.photobucket.com/albums/h298/1951otter/?action=view¤t=7A-1.jpgI did NOT want to go oversize if I could avoid it so I figured out how to fix it my way. i had to weld up the oblonged hole on the pass. top as the original pin slipped UPWARD an 1/8''. this caused that hole to go egg-shape. the restore was to tig the OB side of the hole and carefully re-drill using a smaller size and ream to fit the original pin location straight. the top of each hole has to be just so because the pin is serrated to hold the pin tight in situ. you could if the top is slightly oversized to braze it and the serrated top of the pin would have a snug fit. I used my air die-gringer w/ a 1/4'' rod, the rod end is slit so i can place a length of 1'' sandpaper and spin it to just clean up the rusty dust inside each long hinge hole. BOY it sure seems like nobody ever used any kind of spray grease in any of OUR hinges, Chevy did allow for this but everyone forgets and it's so simple to lube them. I cleaned all the lube holes (for future lithium grease) when i was done & used a bit of anti-sieze and heavy grease as first lube. also cleaned the rust off the old pins on my lathe and gave them a polish. they all turned out super. sorry i didn't take more photos, must have been out of film. (i still have a 35mm camera).
