Quick-Tilt Coil balance

I'm just trying to find the best quick-tilt replacement for two windows. Each are the same size. The original window manufacturer is long gone.

I think replacement sets of the S140-6 will work. I just wanted to verify.

Window Pane Weight: 11 lbs 13 oz

Track Depth: 5/16 inch
Track Width: 1 9/32 Inch

Pivot Bar End: 5/16 x 3/16

The only stamp I could find on the spring is 6Y. Nothing on the shoe mechanism.

For reference. The windows are the Gorell Double Hung G5305 series. Total size from label 35 3/4 x 37 1/2.

Many thanks for your correspondence. Your old components are the 16-024 mounting bracket, the 15-087 pivot shoe and the S180-6 6 lb spring. You are correct that the S140-6 is interchangeable with this system. To be sure, however; we would like to see the pivot bar out of the window sash. Many thanks.

Thanks! Your pivot bar looks like our 26-040, though maybe made by a different company. Fortunately, the 26-040 can work in the S140-6 balance system perfectly fine. I think you should be able to use the S140-6 in your window.
