Which Andersen balances do I need

We took apart all of our different windows and wrote down the numbers stamped on the balances. The pictures we took make it almost impossible to see the stamping but are attached in case you need them.

We need the following:
C1 5 23 573
C5 6 23 873
E2 9P 27 773
F1 10 31 673

Let us know which replacement parts we need for each of the above so we know how many of each to order. Thanks.

We're obviously replacing our balances instead of replacing our windows. It's going to be much cheaper that way and our energy efficiency isn't that bad so new windows just aren't in the budget.

We're so thankful for this site that even showed us how to do this. Keep up the good work!
