Hello!

It appears you have either our S380-28 or S385-28 channel balance. The Series 380 comes attached with a 1" deep shoe, while the Series 385 comes attached with a 1-3/32" shoe. Double check your bottom shoe depth and see which one matches up best. You will also need the 2740 strength option, based on your 27-4 stamp. 

Comparison of the S380 and S385 balance shoes.
