As far as the dials, I don't know, one would have to look and see if it's
the same.  But for calibration, almost every speedometer has a very small
(in height) number somewhere on the dial as to what it's calibrated to.
The number will be something like 980, 1000, 1025, and might have "rev"
after (1000/rev).  This is what the speedometer is calibrated at the
factory to.  Provided it hasn't been re-calibrated to a different speed,
then look for this same number on the 'new' speedometer.  It will then be
calibrated the same as the one your replacing -
