2440 seems to be stamped on the rail. I'll probably replace these sash balances. Need to know which ones to order

Hello,
It looks like you have either our S351-25, with a 15-002 bottom attachment, or S390-25, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need a 2440 spring strength option for your replacement balances. Thank you!
