Smart idea using an extra pulley for the trigger wheel, though cutting the slots uniformly may not be easy unless you have a good milling machine. I paid $40 for one on ebay, incl. a custom hole to fit my small block's pulley. Still thinking about how to do it elegantly on my slant. Making a mount for the VR sensor may be tricky. I saw a youtube video of EDIS on a slant a year or so ago. The bracket was really hanging out in space. It was easy on my small block, using 2 water pump bolts. I made a bracket for both the Ford VR sensor and a Mopar Hall-effect type (from my 3.8L engine). Not sure the later could trigger the EDIS module, and it needs 8 V power.
