Thanks for writing in. Assuming all 3 sets of balances have the same nylon fittings on either end, it looks like you need either our S351-30 or S390-30 for each set. The only difference between these two balance Series is the 'depth' of the bottom nylon shoe, so compare both with your old hardware to see what matches best. For the balances stamped 29-A, you will need a stamp option of 2910. For the balances stamped 29-B, you will need a stamp option of 2920. Let us know if you have any other questions.
