Trying to find the part required. The stamp says 2930 but I don't know what caps I have.

Hello,

It looks like you have either our S351-30, with a 15-002 bottom attachment, or S390-30, 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 2930 spring strength option for your replacement balances. Thank you!
