Sash balance 32 3 stamp option

Contractor from San Francisco Bay Area
I'm doing a repair job of several windows. The existing sash balance is a 32 3 CO Caldwell, and I was planning to replace it with the 33" 385 series. I don't know the weight of the sash. Is there a way of knowing which stamp option I should choose based on these numbers? Thanks.

Hi, other Mike. Based on the stamp of "32 3," I recommend the 3230 stamp option. Let me know if you need any more information.
