I can whip you up a DXF file to have cut if you get me dimensions. Pictured below is my crank wheel setup. I welded a .250" aluminum ring to the back side of my crank pulley, drilled and tapped for a steel trigger. The steel trigger wheel is a .125" mild steel 36-1 that I had cut.

Here's my setup for the cam sync sensor. It's off a Jeep 4.0, mid-90s I think, with an aluminum adapter.
