Can anyone tell me the maker/brand of this sliding glass patio door?

Question

This door is white vinyl 43"x73". It uses the following parts:
(1) Patio Door Handle Set, 3-15/16"; Product Code: 82-035 (exact)
(2) Turning Lever; Product Code: 82-106 (maybe)
(3) Outside Pull Handle, 3-15/16"; Product Code: 82-044 (exact)
(4) Mortise Lock, Round Face, 3-11/16"; Product Code: 82-218 (exact)
Along with needing parts 2-4 above, I also need at least the leading track roller/glide for this door (see attached photos). I cannot see this part so I need someone to identify the manufacturer of this door so that I can order the correct part.
There are no markings on the door or frame but the double pane glass used in this door has GUARDIAN etched on the bottom right corners.

I'm afraid I cannot identify the roller based on this information. I am also not sure who the manufacturer is. Many vinyl door manufacturers use the same locking mechanisms, you see.

I think it would be best if we see a few pictures of your rollers removed from the door. From there, we can have a better idea of what you have and what can be used for a replacement.
