Metal Bi-fold closet doors circa 1960s - replace pins and springs

Question

Hi! Asking for help in finding replacements parts for a circa 1960s metal bi-fold closet doors in my co-op. I have 4 sets of these doors. Would love to keep them and refinish the metal to original. Call me crazy.

None of the closets close properly. The bottom "pin" doesn't seem to stay in he track and I always have to pull "up" o open or close the doors.
Perhaps parts have been lost through different owners.

Hope the pictures help. I do not see any "clips" and...I have a wing nut on the bottom long screw/pin.

Thanking you!

Hello! I think we can help with these. Now, your doors are fairly old, so we may not have these exact pins, but I'm hoping one of our more modern parts can be used the same way.

Before we go any further, I'll need a few measurements from you. Specifically I will need the diameter of the pin itself and the diameter of the top part of the cap; that is to say, the part of the cap that goes into the track. That way I'll know what size it needs to be to fit in both the door ant track.

Any other details you can give me would be a huge help, such as brand name or even just photos of the other pin assemblies so that we have a better idea of context. Those two dimensions are definitely the most important, though, so please let me know if you can get those for me.
