Thanks for writing in! We do not carry an exact match for your existing pivot bars but our 17-093 Cam Pivot Pair may be worth considering as a replacement. Take a look over the dimensions and compare them to your existing pivot bars to see if this pair would be a fit for you application.
I'm sorry to say that we do not have a video on how to attach the shoe to the balance string. This isn't something we typically recommend doing. We do, however, have a video that shows how to replace the entire balance system.
Although, the shoes are damaged, it is like the entire balance needs to be replaced. With that said, from what I can see in the photos, it appears you have the 15-233 Blue Locking Terminal.
If you do decide that you would like to replace the entire balance, they will need to be a custom assembly. I am happy to get a quote made up for you, I'll just need to know the length of the channel as well as the stamp imprinted on the balance.
Feel free to reach out with any other questions.
