Thanks for contacting SWISCO. Take a look at our S351-29 or S390-29 Channel Balances. The only difference between these two balances is the depth of the bottom nylon shoe. The Series 351 has a bottom nylon shoe depth of 1", whereas the Series 390 has a bottom nylon shoe depth of 1-1/8". Compare with your old parts and see what matches closest. Once you know whether you're looking for the S351-29 or S390-29, you should select a stamp option of 2830.
