I have a 66 series 5 Rapier (13" wheels) that I have just fitted an overdrive to. The speedo is showing 100kph and the car is doing 70kph. The car still has the normal non o/d diff. It has a 12 tooth speedo gear. Can anyone advise me what number of teeth and details of the speedo gear to give me the correct speedo reading.
