My patio glass door rollers broke. We think that it is part number 81-257 because it looks like it.
We have taken the door off and we have pictures of the two roller assemblies. Here are the two rollers and two different orientations. One of the wheels is pulled out for illustration purposes.

We have taken off the door and while it is off, we notice that the felt strips on top are in bad shape. We have taken some photos to show the two strips. Two of the photos show the view from the end and you can see the two channels. It looks like it is plastic of metal holding it in the channels. The final photo shows a picture from the slide. it is leaning up against the wall. Finally is a drawing.
These doors came with the apartment which was built around 1988

I agree, the rollers look a lot like our 81-257. As long as the dimensions match I think it's a good choice.
As for the felt weatherstripping, check out our 58-014 and see how well that matches your existing samples.
