They all do the same job... just pulse a signal as the flywheel turns. The mounts are the same on all the motors I believe, but the spacing (from the crank centre) is obviously different, as is the length of harness coming out of each set depending on model. You may find they are different colour wires on different models too, but nothing that's going to tax a rocket scientist!
There's stacks on Yahoo! Japan. Buy a couple of sets to hedge your bets.
