That's right ... if it were tire size, it would be off a certain
percent NOT a consistant amount at all speeds.
Thanks to all that replied and helped me !!!! I removed the dash
'bezel', removed the plastic instrument cover, and repositioned the
needle. It took me 8 or 10 tries, but now it is dead on !!
By-the-way, aren't those handheld GPS devices FANTASTIC !! I
borrowed my sons (he uses it for fishing) ... it has a view that
displays a speedometer/odometer ... unbelievable !!
... THANKS again !!
