Almost forgot - hopefully the Ignitor was gaped correctly.
Very near the ignition, from under the dash, you might see a pinkish wire which has a bullet connector on it. This plugs into another wire leaving the ignition directly. You could call that a pig tail wire and that is where the resistor wire starts. My 65 has a Pertronix II with a new ignition wire connected to the Flamethrower coil, through the dash grommet and connected to that pigtail after removing the resistor wire. Was a seamless operation.
