I couldn't match that number up to anything, unfortunately. There's a good chance those numbers have no correlation to the rollers in any way. In order for us to help, you will need to remove the roller assembly from the door and show us a clear picture of it without obstruction; we specifically need to see the back end, top, and sides. Dimensions would also be a huge help.

I know that's more of a project than you had in mind, but that's just how patio doors are designed. If you want to find the right roller then you have to take the old one off, first. That's the kind of project you have to be prepared for here.
