I think I need new rollers

A quick learner from Harleysville, PA says:
I placed an order for replacement, but now I want to make sure I'm getting the right part.
Pulley outside diameter: 1.16"
Pulley diameter at bottom of V-grove: 0.84"
Thickness: 0.55 (but it's hard to tell because it's so rusty). Without rust it might be 1/2"
What do you recommend, based on these pictures?
