Replacement channel balance
Thanks for posting! These will need to be custom/special order balances, given that you have a wheel in the shoe; they are Extended-Travel Balances.
I am not able to see the clip or hook attached to the shoe of the balances in your photos. These balances typically have them, so if your balance does not, you'll need to find an undamaged balance. They are important for not only identifying the right replacement but also to properly install the balance.
Keep in mind, custom orders are non-refundable and non-returnable. So it is important to confirm which clip/hook your balances have.
Once I have this information, I'll be able to get the link sent over so that you can purchase your balances.
Feel free to reach out with any questions you may have.
