I'm not sure it's possible to re-calibrate a speedometer. I've never
taken one apart, but I beleive there is some arrangement involving a
spinning magnet. The reading is a function of how fast the magnet
spins. There is also a return spring that brings the needle back
to zero when you stop. Maybe that could be "adjusted" if your real
carefull about it.
My 69 MGB reads about 65 at 60. One review I read in some
book or other called MG speedometers "scandalously inacurate". :-O>
