Hey there!

Thanks for reaching out to us. Take a look at the S380-27 or S385-27 channel balances. The best match will depend on the depth of the bottom shoe so you'll have to measure as shown below.

For the 26 2 balance, you'll want to select the 2620 stamp option.

For the 26 3 balance, you'll want to select the 2630 stamp option.
