I want to find correct part #

Thank you for reaching out to us. We can definitely help with this. It will just have to be a custom order due to the 86 stamp. That tells me that your balance has a special calibration that isn't matched by any of our standard parts. I'll go and email you a purchase link and price quote for (2) balances that you can use to place an order on our website. There is a 5-6 week lead time.

Please note that a pair of these balances with this stamp is calibrated for a sash weighing 19 to 22.99 pounds.

I'll be here if you have any questions!
