Speedo Cable Gear
Hello all,
The speedometer on my 1969 F100 4x4 hasn't worked since I bought the truck and I'm finally getting around to fixing it. I've narrowed the problem to the speedometer cable gear--mine has worn a dip in the middle of the gear, so I don't think it's engaging with the one in the tranny anymore. Does anyone know how many teeth my replacement should have given the following data:
Tire Diameter (rolling): 33"
Tire Circumference (rolling): 103 2/3"
Rear End Gear Ratio: 3.70:1
Transmission: 4 Speed Manual with 1=granny
Thanks in advance for your help!
