Thanks for your patience during this busy season. It does look like your spiral balance is broken, so it would be a good idea to replace it anyway. Whether that's the cause of your window being uneven is not something I can say for sure, but it is likely.
Given that this is a typical tilt window, you only have two options: the 3/8" diameter Series 900 or the 9/16" diameter Series 600. Measure the diameter of the balance's metal tube to verify which one is best.
