reinforced 9.5" diaphragm clutch
To convert from the original 9" coil spring clutch to a 9.5" diaphragm clutch you would need to drill to additional holes in the flywheel to accept the extra dowels which locate the clutch pressure plate. The 9" clutch only has two locating dowels but the 9.5" clutch has three. This needs to be done accurately to ensure that the clutch remains central on the flywheel.
The 9.5" clutch kit comes with a taller release bearing to compensate for the difference in height away from the flywheel between the original clutch and the 9.5" version.
