Thanks for posting. This is a bit of a special balance, and I think it will need to be custom made. Before we begin, can you tell me the width and thickness of the shoe? Can you also give me the width and length of the metal channel? Also, how many of these did you need?

Thank you again for your patience. We finally determined that we can custom make these, however there is a minimum purchase quantity of 6 per balance, due to their special nature. Would that be okay? I will email you a custom order link for six of each, including a price quote, for you to review.

Unfortunately, these balances have been discontinued in recent years and are no longer a product that we can supply. I am very sorry for the inconvenience.
