    Upgrade from prestolite to pertronix or replace dist. with delco voyager

    If you are dead set on replacing the mechanical switch (points) with an electronic switch for your coil. I would skip the pertronix and go straight to the voyager. In both cases that I went pertronix, they failed and had to go with points. However the points lasted about 10-15 years with a...
