Need Part number for new Balances

Hello,

It looks like you have either our S351-30, with a 15-002 bottom attachment, or S390-30, 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 2920 spring strength option for your replacement balances. Thank you!

Sure, the part shown in your photos resembles the 18-196 top sash guide pair. Look over the dimensions below to confirm that they match up to yours and let us know if you need anything else.
