Speedometer drive gear

[Terry,OH]

Have you checked the diff. ratio? Being a PU you could have 4:44 ratio. Yes there are a few different speedo turtles for the torque tube speedo drive based upon rear gear ratio and tire size. 2-1 NO. The original speedometers are very much standard. The trip odometer will not work if the reset knob is in the reset position. If your regular odometer does not work there may be stripped gears.
