    Does the transfer input on 72 Fj40 have 29 teeth? Thinking about installing a new Fairey overdrive unit that calls for 29 teeth.

    Thanks

    the teeth count would be 29 or 31 for one piece cases. check here

    as for the input gear splines: 3 speeds are 10 spline, 4 speeds(early one piece cases) are 16 spline and IIRC split case are 19 spline.

    10 spline 29 tooth three speed
    16 spline 29 tooth early four speed
    16 spline 31 tooth for the rest of the one piece transfer case era
