Hello,

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. We'll just need to confirm the number of balances that you need, with the minimum being two, to send over an order link and price quote. Also, your metal channel should measure exactly 27-7/8" long, not including the end fittings. 

Thank you for confirming. We just sent over an order link for you to review. Take a look and let us know if you need anything else.
