      We bought a rebuilt OD transmission to upgrade our ’63 series II from a gentleman in England. Included with the transmission and wiring, etc. was a speedometer.
      The mechanic that is doing the install-who is actually very knowlegable of foreign cars-is at a loss as to why a new speedometer is necessary.
      Anyone have any input on this matter??

        The gearing is different on an OD speedo….Top gear is 1:1 in a regular 4 speed and overdrive is a differnt ratio….speedo is geared different so it will be accurate at highway speeds in OD
