Anderson window balances

Hi, my name is steve. I need to replace several of the Anderson window balances in my windows. I found your you tube video very insightful. I have two different size windows throught my house. After removing the top plastic pieces, I found the following numbers on the existing broken balances:

E 90 9 # 27 80 & D 96 7 # 27 7 79
11600 - 2 11600 - 2

Please help me identify the proper replacement balances. Thanks!



D 96 7 # 27 7 79
11600 - 2
