replacement parts small window

Hello,

The assembly shown in your photos resembles the 15-180 balance shoe, which uses the S190 coil springs. You'll need to locate the stamp on the coils to choose the corresponding strength options. These coils use the 15-186 support and 15-182 bushings for installation. Take a look at these parts, as well as the related videos.

As for your tilt latches and pivot bar, we would need to see photos of those parts removed from the window as well to compare to our inventory. Thank you!
