Slant 6 Megasquirt Ignition (Crank&CAM position sensing)

I am running from the VR signal from the distributor for my spark, so I have no first hand experience, but when I was doing MS research I ran across several people using the Jeep 4.0 camshaft position sensor in the distributor hole (granted this was for small block, I just never looked into MS on the slant). A quick google image lookup of the slant distributor, they ends look similar enough to be worth looking into. If you could machine a standoff for the cam sensor, it might be a clean solution.

Not exactly the info you wanted, just thought it might be helpful if you hadn't seen it before.
