Counterbalance replacement Needed

Home Owner from colorado
Hi,
I need to replace 4 counterbalance pieces for Milgard windows.
The number pressed into the counterbalance is as follows:
86-27-4 GM5 CMC 87.
The attached Photos show the old counterbalance part and a sticker we found in the window. Can you help?
Thank you!!

Hi there, Catherine!

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. What I will do now is email you an order link that you can use to place an order on our website. 

If you have any questions just let me know!
