Hi!
When I am driving around 80 km/h my speedometer shows 60 km/h...
Ive been told my car won't pass inspection when I am taking it to the DMW in Norway to get license plates because of this.
I have a 85mph speedometer, and bought new dust shield, angle drive, lower and upper speedo cable from DMC California back in 2015.
Is the new parts perhaps calibrated to the 140 mph speedometer?
