I only know the part numbers I’m running verses II or III. If I had to guess I’m running II in my 49 Subruban that’s been on the road since 2020 and probably III in my 59 GMC Napco that’s been on the road since 2022.

If mine were to fail I’ll simply replace it with another Pertronix and keep on motoring. I’m not going back to points and a condenser.
