Thanks for posting! I believe we may be able to supply you with a replacement for the bypass door rollers and guides you are searching for but given the age of the door and the hardware, I cannot make any guarantees.
That said, I'll need to see photos of both the rollers and the guides removed from the door to get a better idea of what they look like. Unfortunately, the view of them is being obstructed since they are still installed.
Please let me know if you have any questions in the meantime.
Okay, great! Please feel free to reach out with any other questions you might have in the meantime.
Thanks for the photos! We believe our 23-017 Top Roller Pair and 23-018A Bottom Guide Pair, made for Acme doors could work as a suitable replacement for your hardware. Unfortunately, we were able to find an exact match to your existing top roller and bottom guide; they may no longer be available.
Carefully look over their dimensions and design and compare them to your existing roller and guide. See if you might be able to adapt these to your closet door.
I'm happy to help! Please don't hesitate to reach out with any other questions you might have.
Have a great day!
