Hi Tim,
The web site I found the info on is Deve's Antique Chevy Truck Restorations, under the heading of AD history. I was inclined to think when I read it that he meant to say 3 speed rather than 4 speed, but I wasn't sure. The other specifications he gives such as engine size, horsepower,relocation of the emergency brake, etc. appear to be good. His site can be found at
