M103 Trigger Wheel
 

Anyone know of where to buy a good trigger wheel for an after market fuel injection system. I have a haltech system with a homemade trigger wheel mounted where the distributor used to be but it is not as reliable or accurate as I would like. I am looking for a crank based trigger (either reluctor or hall effect) or information on if it is possible to use the existing crank sensor or the existing flywheel sensor. Anyone have any ideas?
