I've used both 6V positive ground and 12V negative ground Pertronix ignitions in my '49 Club Sedan and both work extremely well with over 1,000 miles of trouble free operation on the 6V version before I converted to 12V. I attribute my good fortune with using it to the fact that it wasn't pairing it up with poor wiring and unstable generation. I had alternators on both versions and new wiring throughout. If you plan on running a typical generator/regulator setup with 70+ year old wiring, stick with your good "old" points and condensers!
