Balance replacement

Hello,

As long as both end fittings are non-winged, you have either the S351-34, with a 15-002 bottom attachment, or the S390-34, 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 3330 spring strength option for your replacement balances. Thank you!
