Here's what I did.
ON the ignition which has the mark, take a tape measure, and measure the circumference of the OD. Then, measure the distance from the raised magnet used to trigger the ignition to the mark.
Compute that ratio / fraction.
Then, with the new ignition, measure the circumference with the tape measure. Multiply the ratio above by the new circumference, and that is the distance the new mark should be from the same spot on the magnetic surface.
As long as the ratios are the same, you're money. no protractor needed.
