I'm joining into this coversation. I was looking for a 6v battery for my 1953 6400 with a 235 engine. Not sure what size battery & cold cranking amps are needed. Just trying to get this truck movable. I also need to install a negative battery terminal. My truck had neither a battery or the neg terminal when I bought it. I see Shaffer's 1950 says his 3100 uses a 1-HD. Would this be the same for my 53? I can't seem to find the specs anywhere.
