I went to the mechanics today to pick up my car, it had the rear end upgraded from a 4.69 to a 4.06 so it can be driven a bit faster without damaging the engine. Thing is it changes the ratio of the gear drive for the speedo. When the speedo says 50 my car is actually going 60. Is there a way to change the speedo drive to fix the indicated speed new gears, recalibrated instrument?
