Hi there!

It appears you have the S351-28 or S390-28 depending on the depth of your balance's bottom fitting. You'll need to measure as shown in the image below to determine which Series is the best match for you. As for the spring strength, you'll need the 2730 option. 

Comparison of the S351 and S390 balance shoes.
