Door hinge pin and keeper parts ?
 

I was just wondering if anyone else might know where to find loads of door parts to repair a 25 year old sagging door , also need the door stay " keeps the door from closing when half or fully opened . Thanks guys and keep it rotating !

Try the junk yard. I am getting ready to try rebushing the driver side hinges on my car. It shouldn't be to hard but I also have a machine shop that I can use. I will post results when ever I do it

i played with this about 10 years ago.

mazda only sells the hinges complete

but they do easily come apart, and there is a bushing in there. the problem was the bushing is kind of a weird size, and all the easily available stuff (gm) isnt really even close.

so its either make custom pins and bushings, which isnt that bad, buy new which is much easier, or you can readjust the door a little higher

What if you just need the springs? In my car the bushings are fine but the springs are a little stretched.

Sorry to thread jack.
