Voltage Regulator - electronic ignition

Both those pictures are of mechanical points regulators.

It's not really necessary to use an electronic regulator but they do work better and are cheap. Go to Autozone and get a #VR706 regulator. Could be under the Wells name or Duralast or another house brand. It will have the same connections but the can will only be 1/2" high. This unit has solid state guts.
