I Just bought a Mark VIII fan and it looks like it will not slide all the way down in front of the radiator because it hits my supercharger crank pulley that sticks out further than a car without one. Most everyone trims the shroud back to install it on none supercharger cars but it looks like it still might not fit if I do that. I do not want to start cutting it up to make it fit and end up messing it up where I cannot use it. Does someone have one installed already and what exactly did you do to get it to clear you supercharger crank pulley?
