Pushbutton -

I'm confused. I've heard of a number of '55 owners converting to negative ground and not having to do anything to the starter or torsion level system.

While I've not done such a conversion myself, I believe one only needed to replace the voltage regulator and repolarize the generator, but should also replace the coil with a universal or negative ground 12-volt unit (for best performance).

Meanwhile, the '56 T-L compensator control was promoted by the factory as the replacement unit for the '55 cars, but you needed to purchase and install an adapter pigtail. Perhaps that pigtail accomodated any polarity issues, but I haven't had time to investigate that. Can you elaborate further on the need to alter that control when changing to negative ground?
