No name or part numbers on this item

A quick learner from Jacksons Gap, Alabama says:
This is the roller that holds my screen door on my Pella patio doors. When I removed the roller rod, two of the four plastic wheels fell off. I would like to know part number for this item. There are two black plastic pieces on the bottom of the screen that keeps the screen on the track. These are spring loaded. I would like this part number also. I have three of these doors that are at least twenty years old. Should I replace these parts on all three doors?

The roller rod that holds the screen is 26" axle to axle?
