Hey there. Depending on the depth of your bottom balance shoe you will go with either our S380-30 or our S385-30 channel balance as a replacement. Whichever balance you choose, go with our 2930 spring strength option to match your stamp of "29 3". Let us know if you need further assistance.

How do I find out which of S380-30 or S385-30 is the correct one ?
Thanks/Lars

Measure like this. The Series 380 has a 1" shoe, and the Series 385 has a 1-3/32" shoe. See which you need.
