In the sensor itself? Uhh, I dunno, not much...everything squares up pretty tight.
With the flywheel aligned, the section of the tone ring, that lacks two teeth is about dead smack in the center of the hole for the starter...I'll get you a close-up of that as well.
I never really paid any attention to the LH2.4 flexplate I had on my shelf for the past year, but apparently, about 90-degrees from that blank spot in the tone ring, there's a dowel pin, simply used for a mechanic's reference of TDC....why the missing 2-teeth isn't at TDC instead, is beyond me....but this is all "just what I heard"
I'm at work now!!! So pics this evening.
Maybe you could keep the 1mm thang on all your flywheelzzz, n have a stronger piece for the ring gear, as intended, and make it mandetory that everyone grind their blocks....End result is a stronger piece for the ring gear and a lighter weight engine block...FULL OF WIN!!!
