I have two older (1987) Andersen double-hung windows that have brokem sash balances. The part numbers on the sash balances are: '114 11R 9-89' and '114 11L 9-87', and both bear the number 11600-17. Is the Andersen Sash Balance, 11R, 10SR the proper replacement for me?

The sash balancers measure 3" x 6.75". My windows are 32" x 72". The markings on the glass are:
11 87/0
