Sure thing! I was able to narrow it down to two products: our S390-24 and S351-24. The only difference between these two balances is the depth of the bottom shoe. You'll have to measure yours and refer to the dimensions we show for each part to determine the best choice.

A handy person says:
thank you very much! i didnt notice that there was all that information on your site before i sent the inquiry ha, so sorry to waste your time, I did find the correct ones yesterday and ordered the S390-24 from you and they have already shipped out!
