Spring loaded detent for guide rail

A home owner from Columbus georgia says:
The picture shows only one but there are two detents that ride in a guide rail on top while the bottom has two plastic wheels that roll in the bottom track.
This is door off a German made shrunk and am needing two of these spring loaded top pivots.
The width is about 1".
Which parts should I order to repair this door?

Hello there!

Thank you for reaching out to us. I'm afraid we can't identify your hardware based on this photo alone. We would need to see photos of the top pivots you're searching for. That will help us confirm if we can help or not. 

A home owner from Columbus georgia says:
The plastic tips are broke off that's why they're not there.

I'm afraid we won't be able to help without seeing photos of the original parts in question. This isn't a door that we're familiar with so we must have the old parts to go off of as a reference. I am very sorry for the inconvenience. 

A home owner from Columbus georgia says:
Here are two pictures of bi fold doors and those spring loaded detent guide pins.
Hopefully this will put it in better perspective.
