constant force balance springs

A quick learner from USA says:
The constant force balance spring for my vinyl window is broken. The window manufacturer was Republic Windows of Chicago, now defunct. The window measures about 35" square.

I have attached a few pictures that I hope will be helpful. The marking on the spring is #9.0 35" P, PAT 5232208.

I recommend you look at our S160-9 coil spring and see if this is a match.

Thank you. I will give this a try!
