Hello,

It looks like your balance fittings are non-winged, which would be replaced by either our S351, with a 15-002 bottom attachment, or S390, 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 2540 spring strength option for your 26" replacement balances and 2830 options for the longer 29" balances. Thank you!
