Bi-fold door, guide

A quick learner from Setauket, NY says:

The bottom guide of this metal, louvered door needs a new guide that has a nylon tip, it's worn off completely. I cannot find any labels that have the name of the manufacturer, but they were located in Roseville, Michigan. The doors are very old. I'm the second or third owner. Also I'm somewhat handy but not sure how to replace the guide pin. Does the door need to come off completely? Thank you for any help you can provide.

This might be a match for our 21-005  pin, but I'm not sure. You will need to remove the door to compare our photos and dimensions to yours. That will be the only way to confirm.

The two top door pins should be spring loaded, so to remove the door you would just pull down on the pins to disconnect the top of the door to the track.

Thanks. Will remove door to find out if your pin is usable. Thanks for your help.
