    Default Speedometer gear

    I'm having a hard time trying to find out the number of teeth that would be on a speedometer gear in a Borg/ warner t10 in a car with a 4:11 rear. Any help with the number of teeth or the color code of the plastic gear would be appreciated. Thanks, Frank

    24 teeth, solid yellow.

    1956-1960 part number 3708143.
    1961-1967 part number 3860347. (Looks like it fits both BW and Muncie)

    From October 1972 parts manual.

    Both gears are plastic. Are you talking about the drive gear on the output shaft or the driven gear in the end of the cable?
