I know where you are coming from with the old school. Never thought of a Pertronix conversion, could work well and maintain the looks of the Mallory. Wonder what it is like to get a cap and rotor for these now? I was just thinking of the popularity of these cars for the exhaust system. Good idea on the OD as well. Have you had any experience with these trans? Imagine shorter driveshaft or just a shorter tail housing and a couple of wires to it. But could be a rare item to find in these parts.
