Thanks for reaching out to us. Can you confirm that you're only measuring the metal channel? I ask that because the metal channel should measure 31" long based on your stamp, not 32-3/16". Is there an identical window in the house so that you can check that balance's length?
The balance shown here will have to be a custom order since it uses the 15-197 shoe. We will just need you to weigh the window sash and get back to us with the precise weight in order to determine the proper strength option for your replacements.
Thank you. We can custom make you the Series 751 with the 15-197 shoe and 30HD stamp. A pair of balances with this stamp will support a sash weighing 23 to 29 pounds. However, the length of the metal channel will be 31", not 32-3/16", long. We can't promise this balance will work for you if the metal channel length differs so you may want to check an identical window in the house to be safe since custom orders are nonrefundable.
With that said, I'm going to email you a purchase link and price quote for (2) balances made to the specifications that I mentioned above.
Sure, I'll email over a purchase link right now for your requested quantity and stamps.
