Robert, I  have a 72 TR6 with a Pertronix but 72's do not have ballast =
resistors.  Therefore, I'm not positive of what I'm about to say, but it =
is my recollection that the ballast resistors in the later models are =
actually in the wire (positive,  I believe) going to the coil.  I'm not =
sure what  they mean by "in front" of the ballast resistor.....whether =
that means between the ignition switch and the resistor, or between the =
resistor and the coil
