Pivot shoe

A handy person from Chicago says:
I was wondering if you can help me identify the pivot shoe for my customers window. It looks like it's a series 600 spiral balance. But I'm not sure? I will need to replace the balances and the shoes, so can I just order ones that are compatible with each other? Thanks for any help you can provide.

It's hard to tell what your shoe is based on these pictures. Can you tell me its width and thickness? Those are the two most important dimensions.
