I am looking for ribbed channel balances with these shoes also shown. I found the shoes, part number 15-194 but I can't seem to find the correct ribbed balances in the right size. Can you please help? Larger balance has 34 B stamped on it and smaller one has 28 D stamped on it.

Thank you!

Hello there. We can replace these balances, but they actually use our 15-230 shoe, not the 15-1943, and they have to be custom built due to their skinny metal channels. Fortunately we can do this for you without issue. I just sent you two custom links via email, one to order a pair of the balances stamped 34B, another to order a pair for the ones stamped 28D. Let me know if you have further questions.
