Window sash channel balance

A quick learner from delaware says:
25" length, channel is 1/2" stamped with 2410. Top plastic part broke has 6603 stamped on it (I had another one break). Windows were installed in 1980.

It looks like the balance you need is our S370-25 with a spring weight of 2410. Let us know if you have any other questions. Thank you!
