Over 10k miles on my 45 GMC with the Petronix unit. No issues. I keep points and rotor in the glove box. This truck is 6 volt positive ground.
I just added Pertonix to my 49 Suburban, this truck is 12 volt negative ground. Huge improvement over the stock points system . I'll keep you all posted.
In your glove box, do you also have?
A condenser.
The screws to hold the condenser and the points in place.
The Bakelite insulator for the distributor wire.
The special tool for the special screw on the Bakelite insulator.
A wire to go from coil to distributor.
The correct coil for points.
I used to run a Pertonix in my '50 235. It worked as good as a new set of points, but no better. It is just an electronic switch which does the same thing as points do.
The good thing about them is, that electronic switch does not degrade from use as time goes by like points do.
My Pertronix unit failed on me and left me in a bad spot. I am lucky that my truck did not burn to the ground. If the key is left on, the unit will cause the coil to get so hot that the plastic end of the coil will melt. So I was out over $200.00 and dead in the water. You can't buy Pertronix units on every street corner. You can buy points, condenser, and a coil on most street corners.
Don't get me wrong. I am happy for your success with your Pertonix.
