Ok, got some pics taken...

Not really sure why I measured everything, but figured it wouldn't hurt. This is out of an '01 3100.

Decided to have some fun in AutoCAD tonight. If anyone has a crank sitting around and cares to try to verify any of these numbers, that would be great. If everything is correct, then maybe we can use the CAD file to get some external crank triggers made...

Hey Brad,
Nice drawing....I have been thinking of drawing one up for a while now. What does your TDC reference mark line up with? Is that the place on the trigger wheel the sensor lines up with when cylinder #1 is at TDC, or is that just the location of the key in the crankshaft?
