12 87 Andersen balance?

A handy person from Vergennes, VT says:
I need some replacement sash balances for our Anderson windows & I'm not sure what to get... so I saw your youtube tutorial and pulled back the plastic and recorded these numbers...

My sash balance numbers:
and S8103/12 87

or it could be S81031 12 87 but the one following the 3 is a long line that does not look the the one after the S8

I'm guessing the 12 87 is date of mfg since that's about the age of the house.

Hello! I believe the key stamp here is "1031." With that in mind, I recommend our 24-1033.
