With just a little creative machining, the pickup coil and module from a large-diameter HEI distributor can be adapted to work with your original point-type distributor housing. That would solve the body clearance problem and keep an original-appearing distributor in place with the vacuum advance as well. A high-output coil like a Mallory or Accel could be used with that setup if you think you need more secondary voltage for some reason.

That's called Pertronix.
Joe is going to try new parts from Speedmaster, get a reading on the brown wire vs orange and try the unit again. He will post the results I hope.
