Replacement of Anderson window balancing piece

Question

Our house was built in 1987. The balancing cord for one of our windows has snapped. Picture enclosed. I don't see 13R, 13 L or 12 SR stamped on the part. I presume your replacement part will fit. Can you confirm?

Thanks for writing in. See our 24-939. This Andersen balance is meant to replace old balances that include the stamp code 927, or 9#27.
