Window sash balance replacement

Question

I need to replace several of these window sash balances. But I'm having trouble identifying a good fit. The length of the metal bar (not including the plastic) is 30 14/16 inches. An help would be great!

Thanks for posting! We have a few possible replacements that come to mind. To narrow down the exact balances you need, I'll need to see a photo of the pulley system in the center of the balance. This is where the spring and string meet in the middle.

Please also confirm the measurement for the depth of your bottom shoe. I'll need to see this measurement written out.
