I need 2 complete assembly replacements. These are not free rolling anymore... after 35 years!!!!... but the door & support channel are just fine.

I'm very confident we can get this roller for you, but the problem is that you're just showing me the internal portion of a complete roller assembly. It appears to be missing the external housing, which is probably still in the door.

Odds are what you have here is our 81-128. I would even bet on it, but you should check your outer housing just to be 100% sure. There are other possibilities so it's better to check now. You can see specs for the 81-128 below for comparison and confirmation.
