What did most of the guys run for transmissions in the gasser classes? Did they run 4 speeds or Automatics? Trying to figure out what to put in the Henry J. I have to admit I was thinking about running a 5 speed so that I could put a little gear in it & still be able to cruise but I do also have a overdrive here as well. I just kind of wanted to stay period correct if I could even though I know that a 5 speed isn't period correct. What I'm meaning is the type of trans (Auto or manual) that most guys ran back then.
