Stanley/Monarch safety mirror closet

A home owner from Connecticut says:
Hi there,

I am trying to locate the small plastic rectangular piece inside the track of the rolling stanley/monarch mirror closet door. It has a circular piece int he middle that a cylinder metal part from the top and bottom of the mirrored doors slots into but they are very worn down and some are missing. I need to get about 4, can you help at all. Much appreciated i cannot find any contact for the company stanley/monarch and the phone number has now been recycled to a healthcare company? Any help would be much appreciated thank you

It's tough to tell what this guide is from your photo, but it is similar to our 21-174. Look this part over and let me know what you think.
