From a personal screw up, I installed a coil with the two primary wires backwards on a '65 - and it would burn a set of points out in just a few days. A bad condenser will also cause points to fail. Also, that new ballast resistor in the system - even new ones can be bad allowing too much current flow. Most of these older cars ignition parts are now made 'elsewhere' in the world, and in places with less QA.

Why not consider changing over to something like a Pertronix - they will keep a stock appearance but be an electronic breaker less system (Ignitor)
