Need sash spring balances

Thanks for posting! I am confident we can supply you with the replacement balances needed for your repairs but I'll need to see one more photo to determine the correct recommendation. May I please see a photo of the pulley system in the center of the balance? There is where the string and pulley and the spring meet in the channel.

Please also confirm the dimensions for the depth of your bottom shoe. It should either be 1" or 1-3/32".
