Upper and lower rollers for sliding screen door

Upper and lower rollers for sliding screen door, the kind on regular patio sliding doors. I've looked through your zillions of photos and have not been able to find these. I attached four photos with dimensions plus one of the handle on the glass slider in case it might identify the manufacturer. I could find no name on any part of this assembly.

Thank you for your assistance!

Thank you for your reply. In an effort to not have this project in my face for too much longer, I spent an hour in my shop and with a pair of generic rollers and some scraps of high-density polyethylene I made a new set. They work great!

Thanks again for your effort.
