    I have asked Ferrari UK for these figures but they will not give them out. Does anyone know what the correct tolerance should be between the splined shaft (1&1/4") and the centre boss of the clutch disc,and also the rotational tolerance. I have been told that it is typically 10 thou for the former and 0.5 percent for rotational.
