Hi there!
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 a spring strength option of 2740.
If you have any further questions just let us know!
