I'm still slowly working on collecting parts for my build, had a few set backs.. like having a baby. Clutch has been an issue for me as AP don't make the clutch any more. Burton and others do sell Helix clutches but lacks information like torque on the listings, not even stated on Helix's website. I emailed Helix to find out what clutch I need as a replacement for CP2000-35 and they put me in touch with one of their distributors. They said the can provide a 6 paddle helix clutch kit rated at 363 Nm torque. I bought a kit and took about 3 weeks to manufacture, they arrived today. Obviously haven't tried it yet, but if helps anybody the part numbers are 77-5076 for clutch plate, 60-5077 fir pressure plate & 40-2034 for bearing.
