Hello,
I would recommend starting by comparing the specifications of the S751-28 channel balance with a 27HD strength option to an undamaged balance assembly. Thanks for posting!
Could you elaborate regarding exactly what part of the balance is too big, as well as confirm the exact dimensions that you need?
Could you confirm the exact dimensions of an undamaged knife lock shoe compared to the measurements shown in the diagram below? Thank you.
Unfortunately, we have not been able to locate a replacement knife lock shoe with the dimensions you've provided. If you'd like to send back the balances you've purchased so far, our return policy can be found here.
I'm sorry that we won't be able to assist with this repair but please let us know if you have any other hardware questions. Thanks for posting!
