Crank Sensor Assembly
  This ia the chisel point sensor from Electromotive.  The part number is shown, I'm told it is available from auto parts store but haven't researched that. 
  Bracket holding sensor is made from  piece of 3/8" 6061-T6 angle and 3/8" plate aluminim.
  The 3/8 plate was drilled to except sensor & slot was cut so it could be compressed with top screw. Plate is secured to angle with (3) 10-32 stainless screws, 2 thru back & 1 thru bottom. Small screw on bottom keeps assembly from rotating on block.
  (1) Tappered flat head hex screw thru bottom is shown by thumb, (2) hex head screws thru back, on right.
  This is a 60 tooth 6" trigger wheel from Electromotive.  The center was cut out to press fit onto the back side of the crankshaft pulley.  (4) 10-32 screws will permanently secure it to the pulley when timing position is determined.
  Bracket is mounted using the 10mm bolt hole in the small machined area on the block.  An 8-32 screw keeps the bracket from possible rotation
  Front side of crankshaft pulley with trigger wheel mounted behind it
