Thanks for posting. I recommend that you look at our Series 500 spiral balance. This hooks on a bracket at the bottom of the sash. If you also need those bottom brackets, I will need to see a picture of one removed.
Based on your information, I'd say that the tube length should be 32". You will need to to physically measure the balance tube to confirm, though. You will also need our 75-005 charging tool, to charge balances. Check out the guide below for instructions on how to do this. Come to think of it, you might want to charge the balances purchasing new ones. Honestly, these balances last a long time. Sometimes all they need is a few turns and they can work as good as new for a long time yet. |

Yes, the top outer sash is often shorter than the lower inside sash and uses a different length balance.
Don't forget a charging tool, 75-005 and for the bottom bracket, use 17-012 . For the felt, take a photo of cross section with measurements, we would be happy to research a replacement weatherstrip for you. |
