Replacement parts for door mirror door rollers

A home owner from Arvada Colorado says:
I have gone thru the PDF for all the door rollers, but have been unable to pin down which rollers I have. I need to replace all 2 rollers in 4 separate doors. The Mirrored Door Rollers I am looking for look like the attached photo, and I could not find any part number for them. They are nylon rollers, and maybe it is the 4332, but I am not sure. Could you help me figure out which one it is, so that I can order 8 of them? Thank you.
