    I changed the gears in my rear end from 2.73 to 3.42. Now, my speedometer is off. It shows like 55 when I'm only going 40 for example. How do I know what size gear to get for my speedometer? I have a standard TH 350 w/ 15 inch wheels running 245/60 R15 tires and 3.42 rear end.

    Thanks - Shane
