Screen Door Top Roller Assembly, HiLite

Can someone identify this screen door roller? My home was built in 1977 in mission oaks camarillo ca. My local ace hardware does not recognize it? Thanks for any help

Hi. I have an old sliding screen door. The bottom rollers look like product 84-032 that you have. What do you think based on the images? I'm unsure about the top ones though. They don't have wheels, but a similar spring mechanism to push up/down to go into the hinges. Do you sell those too? ... (cont.)

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. ... (cont.)
