Hello there!
Thank you for reaching out to us. We can help supply this balance but it will have to be a custom order due to its configuration. The pulley wheel is built into the bottom fitting itself and this balance features an extended cord travel as well as a metal channel length ending in 5/8" which is what makes it custom. For example, the metal channel should measure 21-5/8" long. Custom orders are nonrefundable so you may want to double-check just to be safe.
In the meantime, I will email you a purchase link and price quote for 2 balances that you can use to place an order on our website.
Please note, the top fitting for the replacements will have "wings" but this won't affect function. I just wanted to give you a heads-up!
