Replacing Channel Balances on three windows

Hi, I would like to order new channel balances for 3 windows. The balances are labeled as 32-5 GA2 CMC 5. I measured them and iit appears to be a 33 inch balance. I believe I need your 33 inch series 385 Channel Balance but not sure of the sash weight. Can you assist based on the pictures provided. Really appreciate it, Lou

FYI - As a follow up to my question, I just weighed the Sash and it was 28.2 pounds. I found on youtube to take the window sash out and weigh it on the scale. And the rod is 1/2 inch (9/16 actually) in Thickness. So I think I need to go with the 33" Series 380 Channel Balance Option 3250. Please let em know your thoughts if this is the right choice. Very Appreciative, Lou
