I got the earliest model from PTF when they teamed with spec. When others were having issues, we had none. All the issues are sorted now. Just order the twin disk with sprung hubs, and the SMFW in steel. Make sure whoever installs it, does it CORRECTLY! The tool spec gives is not good enough, you need two tools for the twin disks, the factory tool, and the spline alignment tool. Assembling a clutch, and installing it, takes care, and knowledge, most clutch issues we are are when its not done right
