Hi, Mark.

It appears you have either our S380-29 or S385-29 channel balance, depending on the depth of your bottom shoe. The Series 380 has a 1" deep shoe and the Series 385 has a 1-3/32" deep shoe. Measure as shown below to see which one matches up. You will also need the 2840 spring strength option. 

Comparison of the S380 and S385 balance shoes.
