I still have one of Andys reluctors but after that I want to either redrill one on a drill press or look at altering the rotor/shaft groove/tang to shift the rotor or possibly rotating the flat plate on the inside by widening the groove the locating pin sets it at & widening the 2 holes on the housing outside where the 2 screws secure/locate the plate & seeing how(if) that affects the mounting of the vac adv.
