Looking to replace two of these rollers. Has a metal housing with a nylon roller and a nylon gear type adjuster shown here broken away from the top opening.

I'm having trouble finding this. Could there be more to this roller? If so, I'd like to see the whole thing. Seeing an undamaged version would also be a big help.

It looks a lot like the inside of 84-020. Also, original Andersen screens used hollow axles like this one.
