Hey how do you like the sliding clutch? I bought one for my OS RZVBO1 and it wouldnt work because the clutch without spacing on the inside was too far out, so when I tighned the outer fastener, it wont spin! (the outer fastner is clamping the whole assembly from spinning). Do I need to use the Fioroni clutch bell with the sliding clutch so the spacing is right?( I am using a Mugen clutch bell)
