Barry, I believe that the current ballast resistor on the car should be OK in
lieu of the wire as on the later ones like mine. You should not need to touch
anything there.
Sounds like you want to use drive resistor ? Most of the Lucas units were
replaced at some time with Crane (Allison) or otherwise or in my case
Pertronix. Personally I would try to get a Crane or a Pertronix or other more
modern ignition system.
If you really want to use the Lucas stuff, I do have the old drive resistor of
my '76 somewhere I can look at for you ( maybe even be persuaded to part with,
as it's of no use to me) but I still think you would be better off with a
modern system less prone to problems.

Subject: Distributor wiring
I just purchased a later model Distributor from a 1500 with the integral
ignition module on the side to use on my 1970 1300 Spitfire. I am wiring
the whole car up myself so that isnt a problem. The problem I do see is
that on the wiring diagrams that I have for the later model Spitfires there
is a ballast wire AND a drive resistor the drive resistor is $40 which
seems a little pricey! Can anybody tell me the resistance of this unit or
if it is the same as the ballast resistor that I will be using instead of
the ballast wire currently used on the production Spitfires. In other
words, can I just use two ballast resistors, one for the coil and one for
the drive? If I know the value I may be able to just buy a 5 watt
wirewound resistor to use for a whole lot less than $40
As a side note, just exactly what is the drive resistor used for in this
application anyway?
