Hello,

It looks like you have either our 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. If you have other balances stamped with 2120, we also offer the corresponding strength option on our product page. Thank you!
