Sash replacement for Anderson Window

A quick learner from Leechburg, PA says:
Hello! I need the sash replacement for an Anderson Window. The windows were part of our newly constructed home built in 1986. The numbers are very difficult to read. I did get 11600-17 and it looks like the other number is 31?5?279-35or6. The visible glass size is 16 7/16 X 21 15/16 in each of the two double hung windows. These windows do NOT tilt in for cleaning. Thank you so much!

Hello! Based on your stamp of "5 27,," we recommend our 24-531 Andersen sash balance.
