Replacement steel roller for screen door

A home owner from Massachusetts says:

I am looking for a steel roller to replace the corroded version pictured on the right. It was mounted /screwed directly to the screen door frame. The closest I have found is pictured on the left, though it appears the roller itself cannot be removed / unscrewed from the mount to which it is attached. I am hoping you can help me source the replacement rollers needed.

This looks like our 84-074 or 84-074N. I've never seen the inside portion by itself. Was the original installation a custom job? I suspect whoever installed the original roller drilled out the inside portion from the outer housing and installed it by itself, though I can't be certain.
