Replacement roller for an Alside patio glass door

A home owner from Centennial, Colorado says:
I am looking at your picture of part # 81-030. I can't tell if this part has the screw mounting hole on the top similar to the mounting holes located on Part #81-095 and part #81-138.

I'm trying to replace the Tandem rollers on a 6'0 x 6'8" patio door manufactured by "Alside" installed in 9/96.

The current part has two (2) 1 1/4" rollers

Thank You.

The hole on top of the body of the 81-030 sliding glass door roller assembly is not threaded. Here is a close up view of the hole.

If you can, upload a couple pictures of your current roller and I will see if I can identify a replacement roller for you.
