Anderson Balance Replacement Part Number

My home was built in 1993. I have several Anderson windows with non-working balances. There are 3 different sizes, and they all have the number 11600A-3 stamped on one side and 11600-17 on the other. I do not see either number on your website.

The widow sizes are as follows: H X W
Kitchen 61 X 28
Dinning Room 61 X 32
Living Room 73 X 32

Can you tell me what current Anderson part # I should order?

Thanks

After reading a few posts with the same number (11600-17) that I posted, I went back a recorded the numbers on the Tabs. Here is what I found:

Kitchen 61 X 28 Both R & L Balancer 831 K66 5 92

Dinning Room 61 X 32 R & L Balancer 1031 BS45 1192

Living Room 73 X 32 R Balancer B037 1192 11R
