Hello. 2 sizes of window, the top and bottom plastic pieces are identical on the two different size window balancers, the balancers seem identical and the widths are identical (1/2 in) but only the length is different.
1. Big window: see pic 2272 for printed part no. See pics of the ends. Sash weighs 23 lb. Metal part of balancer 32 inches.
2. Small window: see pic 2273 for printed part no. Plastic ends the same as the big window. Sash weighs 13.6 lb. Metal part of balancer 24 inches. (surprisingly it's not 23 inches despite the printed part no.)

Hello,
With this combination of attachments, you could have either an S380 or S385 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment.
I would recommend double-checking the length of your longer balance since a (32-2) stamp would normally indicate a 33" long metal channel.
Once that information is confirmed, you'll use the stamp numbers on your balance to choose the corresponding spring strength option.
Thank you and let us know if you have any other questions or concerns.
