Hi Cheezle
Mazy used to have a verto clutch, which we swapped out for a lightened flywheel & pressure plate. There is a different bracket for the slave cylinder and the slave cylinder is bolted to that bracket. That is why the clutch arm is shorter.
The slave cylinder is also different to the standard one, so you have to get the right one. The best thing about the verto clutch is that it is self adjusting.
