deadbodyman Well here a couple pics of what I came up with,in the 35 yrs I've been doing this stuff This is the first time Ive ever done this but it works and it worked well too.I was able to squeek by ,replacing half of the top hinge but bottom one was welded to the door and was wore out bad so the pin just wodbbled around,I drilled it out and shoved a bushing in there now the bottom has 4 bushings...
I gotta thank old bodyman for turning me on to Oriellys for the pin and bushing set,I had givin up dealing with those yahoos the part # came in handy ,he just looked at me like how the heck did you know that hopefully someone will remember this cure if they ever run into this problem and it'll help them out..

malc The lower hinge bolts to A pillar can be loosened for some adjustment, I used a jack to support my doors at the latch end while heaving it into line.
Of course there is a tool for the job.

deadbodyman The problem is theres no adjustment so when you change a door you have to bend the door and hinge until you get a good gap ..so If a pin wears out and someone bends the door to get it to close,when to change the pins and busings the door wont fit any more and things get a little tough,sometimes it takes two people hanging on the door to pull it back down,and then it goes too far down and you have to bend it back up again...

Lizer DBM, I feel your pain on those stupid Chevy hinges. I'll be repainting a 93 Chevy truck for a friend this summer and we were swapping out the doors from his 92. I saw those welded on hinges and hammers and words about started flying. Then I saw you just remove the pins and the door comes out, and it wasn't so bad after all. In fact, I think it's actually nicer than having to adjust hinges.

By the way, I'm repainting my dad's horse trailer, the friend's truck, and perhaps another friend's sailboat this summer. And all of those before the Mustang. They will be called PRACTICE for the one that really matters, since I haven't done base or clear in a few years

deadbodyman Those are pretty cool malc.
Well I came up with something pretty cool and quick for the bottom hinge today,I was able to use the original half of the hinge that bolts to the jamb to replace the worn out half that was on the new door I picked up but the side that was welded to the door was so wore out something had to be done so I drilled it out larger to accept the large bushing so the pin dont wobble around I could have welded the pin but that would have made it hard to replace in the future..so now my bottom hinge has 4 bushings 2 for the pin and 2 where they should be....nice and tight...and no welding ...something anyone can do at home for around 10.00 a pair on the camaro...

malc Here´s what I had.





This is my new greaseable upper, on replacement doors of course.

Yes ,three actually the regular replacement that are ez to get come with two size bushings both have the same inside diamiter ,one set is smooth and the other is bigger and ribbed...The bigger set I've always used when the hinge itself is wore out ,I just drill out the hole to the propper size for the bigger bushing to fit...
The top hinge on this thing has two pins shorter and fatter than any I've seen before all the camarosof this style have them The dealer cant get them but O riellys can order them for ya...

actually the door has to come off anyway (weldedhinges).so even if one hinge was still good (which isnt the case ) I'd still rebuild both...its like installing a clutch without a new pressure plate.The bottom hinge pin is ez to get I did order the new top pins and it was a big help having the part #....


Well stupid me since I had to stop work on the pins till the new ones came inI flipped the door over and coninued work on the skin ,there was some filler still on there that I wanted to grind outand what I thought was a thin layer turned out to be 3/4 " thick and right under the reinforcement bar so I couldn't see any holes from the dent pullerso I went and got another door from the Upull it yard,its almost perfect but the hinges are are really wore out so even if I use the new pins and bushings I'll have to go back to my original plan of of filling the hinge hole and making a new one... pics are coming

deadbodyman The chevy trucks are another good example. I had one come in that got hit hard and folded the top hinge flat....I knew I didnt want to get involved in drilling out those monster plug welds so I dusted off the torches and heated it up and pulled it out nice and pretty I never thought the door would close right again but it worked great and pretty darn quick ,closed right first time...
I'd love to say it was my years of experiance but sometimes its just dumb luck, plain and simple...

These doors are a major PITA to get apart everything is ritited on so just getting the out took way longer than it should have. I sure am glad the pins and bushings are still available though ,I guess I gave up to easy after the dealer said they were discontinued...
You can also weld up the worn side of the hole with a couple of tacks and then grind it to shape with a rotary file. Yeah I a made the mistake to change a pair of those weld on hinges on a Chevy truck once......never made that mistake again!

Holly crap 106.00 to rebuil two hinges and they dont even include the roller and roller pin for the lower hinge...then wait a week for it to get here ...Now you know why I was going to convert it if I couldnt find the proper parts
