Hello,

We'd be happy to help but we would need to start by seeing a photo of the connection between the pulley and spring inside the metal channel. That will help us confirm if one of our stock balances would work or if they'll need to be custom-ordered. Thank you!

Thanks for getting back to us. It looks like you can use either our stock S351-22, with a 15-002 bottom attachment, or S390-22, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need a 2130 spring strength option for your replacement balances. Thank you!
