Recently received a S751-29 (tg28) option. Length and end are perfect but the cross section is to big. See attachment. Mine is on the left yours on right. Any options avaliable?

You have a special type of balance that will have to be custom made. We can make it for you, fortunately. I will email you a special order link and price quote. Let me know if you have any questions, or would like clarification for anything.
