Hi Phil. With this combination of attachments, you could have either an S380 or S385 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. You'll also need a 3150 spring strength option for your replacement balances. Thank you and let us know if you have any other questions or concerns. Comparison of the S380 and S385 balance shoes.
