Missing track and fixed hardware

A handy person from La Grange, Illinois says:
January 25, 2022
I have three metal bifold doors that I would like to reinstall. One door goes in a 36" wide opening and two go into a 72" wide opening. I am looking to purchase the upper tracks and associated pivot mounts, and the lower floor mounted brackets. I do not believe that there was a lower track.

If you are unable to see the photo comments here is a summary. All pins are 5 1/4" long. Metal pin diameter is 5/16". Nylon cap diameter is 3/8".

The doors have no manufacturer information.

Thank you for your time,

Cam

You have the old style Slimfold bi-fold door. The 36" track will be our 21-401 and the 72" track will be the 21-403. These doors require top and bottom tracks to operate properly. 

You will also need the track bumpers, specifically our 21-277 for the top and bottom track. 

If you want to replace the pins, you will need one 21-001 for the bottom adjusting pin and three 21-007 for the other three per door panel.
