Hi, I have a window where the side "spring" i would say is broken. Not sure what the technical term is but I cant seem to find it anywhere. It is a white cassette like part that is on both the right and left side.

It's tough to tell what you have based on these pictures. The stickers don't tell us all that much. I believe you might have our S160-5 and S160-4 coil springs. However, I'd like to see your pivot shoe to confirm.
