27 4 KP CALDWELL

At first glance, your balance looks most compatible with both our S351-28 and S390-28. The only difference between these two parts lie within the bottom balance shoe. The bottom shoe of the Series 351 measures 1" and for the Series 390 it's 1-1/8". You will need to measure the depth of your bottom shoe, like in the diagram below to determine which balance is the best match for you. Whichever one chosen will use a 2740 option.
