Hi, I ordered these from you a few weeks back. I need the same thing but the opposite wheel (concave) . It is 9/16 at the widest 2 3/16 long, and the wheel is 1 1/2 in diameter.

Hello!
Start by comparing your dimensions to our 23-198 and 23-176 to see if either of these match up to the original roller assembly.
