Need to right replacement sash support Andersen window balances

A home owner from Philadelphia, PA says:
The images I have included is for my bathroom Anderson window. I also need the Replacement Sash Support Andersen Window Balances for two other size Anderson window. I did not take the other two out because it make window not usable but I took down the details. The all my original Anderson sash support balance has 11600-17 only the bottom numbers are different. All my original Anderson sash support has the same hole layout and look.

Bathroom window:
Actual window size: Width = 28 Length = 37
Numbers on sash support balance 11600-17 J2 5#23 484

Front Living Room window:
Actual window size: Width = 28 Length = 53
Numbers on sash support balance 11600-17 D31 7#27 2-85

Side Living Room Window:
Actual window size: Width = 32 Length = 53
Numbers on sash support balance 11600-17 D34 7#27 2-85

Please let me know what part numbers to purchase for my Anderson support sash balances. Also, is price for the part on your website for one sash? So, if I need to replace both sash for each of my windows, I would to order 2 qty per sash part, correct?

Please let me know.

Thank you,
John

Hey, John. I have two balances I think you should look at. For the bathroom window, check out our 24-531. This can replace balance boxes with the stamp 5#23. As for the two living room windows, see our 24-737. This can replace balance boxes with the stamp 7#27.
