Need rollers for older Peachtree sliding door

A handy person from Cumming, GA says:
Hi,
The older looking one in the pictures is what I need. The newer one, 81-071, is what I ordered from you but it is the wrong one, doesn't work. I can take the door back down and get measurements, if necessary. Let me know if you recoginize what I have and the required replacement.

Thank you for posting! Could you tell us how your roller differs from our 81-071? What are its dimensions?
A quick learner from Cumming, GA says:
See how the old roller adjustment screw is centered and the notch cut out on top of the roller. I need this type to fit the door. The picture includes my roller and the new 81-071 so that you can see the difference.

Ah, I see. How about our 81-036? Could this be a closer match?
