What part do I need

Hello, thank you for posting,

We can supply your original balance, but it will require a custom order due to the style of the connection point of the spring and pulley system that supports the window sash.

To further review, are you able to confirm the depth of the bottom shoe as measured below? It should either measure exactly 1 inch or slightly over.

Please also confirm how many balances you would need? For custom orders there is a minimum of (2) and nonrefundable. Thank you!
