Sliding mirror door roller

A quick learner from Rockland County, NY says:
I cannot find replacement roller that screws in the top & is wide enough for theses screwed holes. No names or #'s on the parts or the doors.
I'm guessing these are original with the condo that was built in the late 70's. I just sold it so I do not to pay to replace the doors.

Thank you,
Patty

I'm afraid your top roller assembly is discontinued. You might be able to use 23-049 as a replacement. Please compare our measurements to yours and let us know what you think.
