Hi there,
I have an older Stanley bifold mirror door set. The plastic round donut shape slide in the bottom track is broken and needs replacement (the pin is still fine). Do you have the plastic replacement piece?

I am also happy to replace the pin if you have one that fits the same track and has the necessary plastic slide on it.
thank you for your assistance.

This looks an awful lot like the 21-174 nylon roller guide that Stanley used on some of their doors. Is ours the same size as yours?
