Thanks for posting. See our S380-29 or S385-29 Channel Balance. The only difference between these two balances is the depth of the bottom nylon shoe, or the heel-to-toe measurement. See below. Measure your old balance's shoe depth to see what matches best. For a stamp option choose 2830.

Comparison of the S378, S380 and S385 balance shoes.
