Hello,

It looks like you have either our S351-26, with a 15-002 bottom attachment, or S390-26, with a 15-001 bottom attachment. Note that the balance length only includes the metal channel, not the end fittings. Take a look at the image below to determine which option you'll need. You'll also need a 2540 spring strength option for your replacement balances. Thank you!
