Metal bi-fold

Hello I have these 96" bi-fold metal doors that I want to continue to use. But no one carries the parts.
They are same design top n bottom pivot side and opening side.
I am unsure if what is in the only picture part whether is is actual original or not
Top pivot has a plastic cap set in.
The opening side top should have a plastic cap that the part goes into. I see you may have that part.
I am wondering do you know what the original parts are? Do you have them?
If not can you lead me to a place that does. I have 15 doors.

Hello I don't need door replacements I was just wanting parts. Although I wouldn't mind getting a price on a door replacement for future use.

No doors have different pins in bottom
Tracks are good.
Hard to see the plastic cap
But other pic is one I found and one we made to be similar to what was needed
