Sliding mirror, top roller guide

Thanks for posting. Start by looking at our 23-097, this looks like it could be a close match. Let me know your thoughts.

The 23-090 does have a similar housing, but the guide functions differently compared to your rollers. It may still work but I just can't be sure. The 23-097 just installs with screws. If you have screw holes in the frame of your door, as with many doors, you could install it easily enough, but again I cannot be sure. Ideally you could swap housings between these two parts, but since the roller portions are riveted on I don't think that'd be an easy fix.
