Hello,
With this combination of attachments, you could have either the S378, 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 2930 spring strength options for your replacement balances.
These balances, as well as the guides you need, can be purchased directly on our website or by giving our customer service team a call at (888) 991-1929. Thank you, and let us know if you have any other questions or concerns.
