50 Chevy,
My grandfather did the conversion on my 48 Chevy many years ago. It is the same 55 235 with short shaft water pump to the original 48 NP420 4 speed. He had kept it 6 volt, but told me when I was converting to 12 to keep the factory foot pedal 6V starter and use a early 60's Buick or Cadillac generator and voltage regulator. I found a 1961 Buick generator and v/r and had the gen rebuilt. Has worked just fine for the last 8 years, and I daily drive the 48 about 50% of the time. Unless you are a Chevy purist, most people think my truck is bone stock.
Hope this helps, Garry
