Hello there! My recommendation would be our S380-21 or S385-21 channel balance. The important difference between these two parts is the depth of the bottom shoe so you'll need to measure as shown below. Based on your 20 4 stamp, you will need the 2040 spring strength option. Comparison of the S380 and S385 balance shoes.
