Coil balance spring replacement

Hello. I have vinyl replacement double Hung windows in my house that utilize a coil balance spring. Both springs on one window have broken. I note that you have several types of springs and feel confident that you would have the type I need. However I cannot see how the coil could be replaced. It seems to have been attached to a plastic block which is held in a U-channel with a long screw. Any assistance you can provide would be greatly appreciated. The Manufacturer of the window is unknown to me and the contractor is no longer available. Identifying labels on the window: The Door & Window Place.

It looks like our S140-9 Quick tilt series coil balance may be your best option as a match. It comes complete with the spring and pivot and is available in a left or right option. The S140-9 will hold up a sash weighing 17-19 pounds. Take a look and see if this system could work for you.
