What model channel balance do I need?

Hi, Ken.

What you have here is a special type of balance that will have to be a custom order. The key detail here is the stamp; specifically, how your stamp starts with "86." That tells me that your balance has a special calibration that isn't matched by any of our standard parts. What I'll do now is email you a purchase link and price quote for (2) balances that you can use to place an order on our website. Please note, there is a 5-6 business week lead time. 

Let me know if you have any questions!
