Tom,
For a better understanding of the ignition system and the ballast resistor,
you might want to check out this article:
www.team.net/www/morgan//Tech/art023.html
As to weither your car needs one or not, depends on 2 things:
1. Is the coil you have, a ballasted coil or not
2. Do you have a "ballast" or resistive wire in the ignition circuit.
My 77 Spit, had a ballast resistor, but with some of the changes by the
PO, it is no longer in the circuit.
