I currently have a McLeod street twin disk clutch in my truck. It has about 30,000 miles on it. I took my plate out last week and now it won't hold the power. What I am wondering about is the interchangabilty of the Haisley clutch disks and pressure plates. Is the flywheel the same on all of them? I plan on pulling with the truck next summer and would love to upgrade now. Is there a way of upgrading what I have to save a little money?
