need help

Hello, thank you for posting,

We can supply your replacement balances but it will need to be a custom order due to the length, extended travel pulley system and unique combination of end attachments. 

To further review, please inform the number stamped on the metal channel and how many balances you need?

For custom orders there is a minimum of (2) required. From there I can send over an order link with pricing for your review. Thank you!
