My Swisco agent tells me this is a custom on a custom.
I need these balances. The only thing wrong with them is the pulleys.

Hello,

We can supply these replacement balances that use the 15-230 T-lock shoe but you are correct that it will need to be a custom order. To get started, we'll need to see the clip attached to the end of the pulley cord of an undamaged balance. We'll also need to confirm the number of replacements that you need, with the minimum being two. Thank you.
