Andersen Sash Balances

Question

I have (2) Andersen windows (about 35 years old) that need new sash balances. I tried to get a good picture but couldn't, I was barely able to read them with a magnifying glass and flashlight.
Window #1- Balance marked - 11600-17 E39 9127 5-86
Glass measures - 32 3/8 W x 23 7/8 H
Glass Marked - 16CC CBA 311
Window #2- Balance Marked - 11600-17 D53 7727 4-86
Glass Measures - 24 3/8 W x 23 7/8 H
Glass Marked - 16CC CBA 311

Please ID these and let me know if you have the correct replacements in stock.
Thanks in advance for your help!

Hello! The key stamps here are "9127" and "7727." For these balances, I recommend the 24-939 and 24-737, respectively. I am confident that these will repair your windows.
