Sliding Glass Door - 60s

Hello there! Thank you for reaching out to us. I'm afraid it isn't possible for us to identify missing rollers. The only way for us to help is if we see photos of the original hardware, unfortunately. There are just too many options and we have no way of narrowing them down. I am very sorry that we won't be able to assist with this repair but please let us know if you have any other hardware questions.
