Now available is a new electronic speedo sensor trigger wheel.
The wheel has 40 teeth which gives an improved smoother signal over the 6 CV joint cap screw heads usually used to generate a signal.
The trigger wheel bolts directly to the CV joint and can be cut in half to save having to remove the driveshaft and CV joint for installation.
The calibration code in the speedo unit will need to be changed to get the correct readings with the new wheel.
To do this simply multiply the existing figure by 6.666.
The signal is also much cleaner as the sensor is reading on a flat surface as opposed to the curved cap screw resulting in a smoother more accurate reading on the speedo needle.
