It could be our S190-640 coil spring. However, if you would like to confirm, show us a couple pictures of the pivot shoe and spring and we can work from there.

Great, thank you for the new picture. Start by looking at our 15-180 picot shoe, as well as our S190-640 coil spring, 15-181 detent clip, and 15-182 bushing. Keep in mind that you only need to replace what's damaged; you can reuse the other parts.
