Brian, I don't know how many teeth there are and I don't have one here to count, but I really think you're making more out of this than is necessary. Lift the dizzy out and re-align the oil pump drive with a long screwdriver for the new rotor position at one tooth counter-clockwise. Slide the dizzy into position and install the hold-down bolt. Fire it off and see what you have. If it's spot-on, great. If not, it's no big deal to move it one more tooth.
