Now I get too see how long the Pertronix functions before I get stranded like so many other have.
I installed a Pertronix 3 on my 70 El Camino. No problems for the three years before I sold the car. I had an old SW tach (1965) with sending unit that worked just fine with the P3. (Tach is going back into my 68)
