Frank, For the instruments, NAPA carries a regulator that's intended for earlier 12v Ford stuff, but I've used it successfully for my Hudson 12v conversions. The 6v '48-54 Hudsons ran the gauges on about 5v pulsed power supply. This NAPA unit (NAPA/Echlin IR-2), supplies that voltage, with anywhere from 6 to 18v input. It's cheap ... you may want to try one. Park Waldrop C cpe - Atlanta
