The wheels for windows to help sllide

Question

A lot of my windows are missing these wheels. It seems like they pop off and can be replaced to the other piece still attached. And some windows seem to be upside down and wheels on top. But need them on bottom so they can slide easier.

Thank you for posting. This looks a bit like our 87-185 and 87-155. Do you think you could use either of these as a replacement? The wheels seem to match, which is what caught my eye. At the very least, you can pop the wheels off our roller and put it on your own hardware.
