Thanks for writing in! The balances you have are the S795-28 with a 15-198 hook attached to the top of them. These will need to be a custom assembly.
The shoe you have pictured here is the 15-195 closed cam shoe, which can be identified by the closed off metal cam on the back of the shoe. The open cam shoe has a cam with an open hole in it. The replacement balances will come with the 15-195 shoe assembled.
I've forwarded a link with a quote for (2) of the requested balances. There is a bit of a lead time since we do not currently have the hooks in stock. If you would like a larger quantity of balances, please let me know and I'll be happy to update the quote for you.
Please let me know if you have any questions.
