I had to change my 140 vtr clocks to blue dial 120 random saxo clocks, as my vtr digital mileage had went all cloudy, and would not go through mot here in N.I. Does anyone know how to change the mileage on the new clocks to match my vtr clocks mileage, or can the digital mileage part be moved over to my original clocks? Could live with the new clocks if the mileage can be changed, but would prefer if I could go back to my original vtr clocks, as with the white dials and temp gauge, they look far better. Cheers in advance if anyone can help me out!
