need to replace 2 balances

Hello,

We'd be happy to help but we'll need to see a photo of an undamaged channel balance removed from the window to determine the correct replacement for you. The stamp number you provided is, unfortunately, not a part number. The stamp would normally tell us the spring strength your balance requires but since yours appears to be outdated, we'll also need to know the weigh of your sash to tell you which spring strength option to choose. 

Shipping will be calculated at checkout but we do offer overnight and two-day shipping options. Thank you!
