  1. Charlie,

      Let me do a little more investigation to see if the speedometer pinion that came with the 1980 720 transmission is the correct one for my truck.

    Thanks,

    Dan

      The 1980 720 L20B 5 speed uses a 3.899 Gear ratio.  If you swapped the third member from the 1980 Truck then the speedometer should read correctly.

       

      Crashdt420 used his speedometer drive pinion from his 4 speed by cutting a hold down notch 180 degrees from the original notch.
