Hello!

We appreciate you reaching out to us. Depending on the depth of the balance's bottom fitting, you have either the S380-32 or S385-32. Measure as shown in the image below to see which Series matches up best. 

You'll also want to select the 3150 strength option for the 31 5 stamped balance and the 3140 strength option for the 31 4 stamped balance.

Let me know if you have any questions!
