How to determine strength option

A quick learner from Oregon says:
I have two different size windows where the balances need to be replaced. One balance is stamped 32 4 AQ Caldwell. The other is stamped 26 5 LP Caldwell. My tops and bottoms match perfectly with the ones that come with Series 385. I think I need Series 385 33" with option 3240 for the first one and Series 385 27" with option 2650. Do I have this correct?
Thanks,
Paul
