Need Channel Balance

A handy person from Keller, TX says:
I have broken Single Hung Window Channel Balance Spring assembly.
It looks like a series 351 from your picture but not 100% sure.
It is 1/2" by 28" and the number stamped on it is "2790 30 PA".
Between the 2790 and 30 are the letters BSI perpendiculae to them.
Cannot find a name on the window unit and about 7 years old.

Please advise. Thanks, Vincent

Thank you for submitting your images.

Please take a look at the following guide and see if you can identify your bottom balance attachment.

A quick learner from Keller says:
no wings and it looks like 1 1/16 exactly between the two.

Please advise, Thanks, Vincent

You will need to order a S395-28 with option 2730.
