I have taller tires on the truck.
I knew the odometer would be reading incorrectly so I took it to my local ford dealer. They said the truck is to old to calibrate.

The truck has a manual shift five speed transmission.
To fix the problem I thought about swapping the rear end gears.

Can you swap the output shaft speedo gear in the transmission tail shaft?

If anyone has any advise on how to calibrate please help.

Thanks
