The difference is the gear ratio inside the speedometer. Look on
the face of the speedometer and you will find a number that represents the
number of turns per mile; the MKI is generally 980 and the MKII is generally
1020.
The stock gear set requires a tire diameter around 23.5" to be accurate, the
16 tooth gear and a 980 speedometer requires a tire around 22 1/4" diameter.

Thanks Dave
Will check the gear. The speedo has been rebuilt and calibrated. SS list the
Mk1 as having a 16 teeth gear the Mk11 as 17 teeth. I have a spare 17 teeth
gear which I will try, my rolling tire is a bit smaller than stock I think
at 22.5"
The manual lists the Mk1 & Mk11 final drive, diff ratio, and wheel size as
the same. What then is different betwwen the 2 to change the speedo gear
ratio?
Regards
Wally

Get another gear from your Ford dealer. OEM was 15 teeth but
they have been unavailable for years. Next up is 16 teeth. Each
step up reduces the speed reading about 3 mph.
