Confirm that the metal channel, not including the nylon fittings on either end, is 32" long. If so, see either our S351-32 or S390-32. The only difference between these two balances is the 'depth' of the bottom nylon shoe, so compare both with your old hardware to see what matches best. You'll need a stamp option of 3140.
