    My speedo reads 180kmh when the car is actually 150kmh, so it's well past the 5% tolerance.

    On the newer speedometers I know there is an adjustment screw, what about the old "cable speedos" as found in my January 82 car? Before I investigate any-further this speedo is there any possibility to adjust these?
