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!

Comparison of the S351 and S390 balance shoes.

Hi there!
Thanks so much for the quick response.
Now I need more help. I need the part number for the plastic stoper that prevents the balance from going up the window chanel. It goes on top left and right of the window corners.

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.
