Hello! We can definitely help with this hardware, but we only sell the individual components separately. I hope that's okay. See our 15-199 pivot shoe, 1/2" thick S160-3 coil spring, and 15-150D double spring support. I believe these parts are exactly what you want but look them over and let me know if you had any questions!
