need a pair of sash balances for a 3032 Anderson window. C37 6#23 11-77 also for a Anderson window 3046. I don't know the numbers on this balance as I have not pulled it.

Hello,
Take a look at SWISCO product code 24-637, Andersen sash balancer, I believe this may be the needed replacement for the C37 6#23 11-77.
Let us know what the numbers are on the other window balances when you get a chance.

I finally pulled the balance out of the 3046 and the numbers are E40 9#27 8-77. What do I need?

Please take a look at our 24-939 Anderson Sash Balance, which can be used to replace balance boxes with the stamped number 9#27.
