Buchmin closet door roller replacement

A home owner from Denver, Co says:
I am looking for the wheel assembly for a closet door manufactured by Buchmin Industries in 1975. The legend on the sticker is Z97.1 1975 and was on the back side of the door. When I tried to call the number was disconnected or closed. If you help me to find the part in Denver or if you have it in stock I would appreciate any type of contact.

If you have a current telephone number for Buchmin Industries that would be helpful.

We believe Buchmin is no longer in business. The closet door roller assembly you are looking for closely resembles our 81-125. Please compare this to what you have now to confirm.
