single wheel glass door roller

The housing top to bottom is about 1 1/32" and the wheel extends below the housing to a height of 1 1/8" overall. The housing is 9/16" thick, except that the edges of the ends of the wheel axle sit outside the housing and are probably 1/32" wide each.

This is a Michigan Door, a company that I believe is still in business. I don't know when it was installed but it had to be way before 1970.

Thanks for your help!
