Hello,
It looks like you have either our S351-28, with a 15-002 bottom attachment, or S390-28, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need to locate the stamp code on your metal channel to choose the corresponding spring strength option for your replacement balances. Thank you!
I agree that your balance fitting could certainly have worn down a bit over the years, so the balances you purchased should have the correct specifications for your window. Let us know how you make out once they arrive!
