Help determining balance option code for weight

Question

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,

Hey Paul. As long as you're absolutely sure that the nylon fittings on either ends of the metal channels match those used by the Series 385 (the 19-005 Top and 15-004 Bottom Fittings), and so long as the metal channels are exactly 33" and 27" long, then yes, the Series 385 and those lengths are correct, as our the stamp options you've picked. Let me know if you ave any other questions.
