Hello,
We'd be happy to look into this for you but we'll need a bit more information to narrow down your options. If you could show us the connecting point between the spring and pulley inside the metal channel, that would help us confirm if our stock balances could work for your repair or if they would need to be special ordered. Thank you!
Thanks for getting back to us. It looks like you have either our S351-20, with a 15-002 bottom attachment, or S390-20, 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 1940 spring strength option for your replacement balances. Thank you!
