Anderson window balance boxes

Quick Learner from Ann Arbor Michigan
I need to replace both balance boxes to an Anderson window. The stamped number on the boxes is 11600-17. And opposite that is JJ 5#27 3 87.

Which replacement part would you recommend?

Thanks,

Bob

Thanks for posting, Bob. Please take a look at our 24-531 Andersen Sash Balance. I think this should work for your application.
