Hi there!

Thank you for reaching out to us. Take a look at the S378-27, S380-27, and S385-27. The important difference between them is the depth of the bottom shoe, so you'll have to measure as shown below. You can also select the 2630 stamp option for the replacement balances.

Please let us know if you have any questions.
