Hello,

We'd be happy to help but we would need to see the fitting attached to the opposite end of the metal channel as well to narrow down your replacement options. Thank you! 

It looks like you have either our S351-33, with a 15-002 bottom attachment, or S390-33, 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 3230 spring strength option for your replacement balances. Thank you!

Sure, you are welcome to order a pair of S380-33 and S385-33 balances with 3230 strength options to try out. Our return policy can be found here if you'd like to send back the balances you don't need.
