That small 3/16" or less index mark is what they use to originally line up the reluctor, pole piece, pickup peak to the proper relation to each cylinder. Then, they drill the gear and shaft to hold it there. If you take it a part for repair, the roll pin is drilled off set, so it will only fit the right way. What they had at that time was someone not lining them up properly. I believe I have a tech bulletin somewhere on that explanning the fix. Man, I can't type right, hahaha.
denny it will go back the wrong way, trust me it will. i lost a 25.00 bet on that one time
