Try Millworks Hot Rods&Supply Co, Tewksbury, MA 01876. They rebuild 1932-48 Ford generators for 12volts. Maybe someone can tell you someone closer. I haven't delt with this company directly. Be careful with conversions like this because the earlier generators can overheat if built to supply a lot of amps when wound for 12 volts. Also, you'll need a separate voltage regulator. Terry
