Please refer to pictures attached. The most critical measure is the distance between the bolt center that goes through the glass and the inner bottom (if you invert the picture) of the "U" shape that hugs the top of the glass door - that is a bit more than 3/4" (13/16" to 7/8"); I guess this distance could be a bit larger but not smaller.
The mean distance between the center hub of the roller and the hanger shoulder is about 5/8"; however I reckon this is slightly adjustable.
I would be enormously grateful if you can help.
