This brings up a good question for me...I switched from a 2.78 open to a 3.42 posi, and now my speedo's off (but I don't regret it for a minute ) I have a 4 speed M22, but originally had an automatic years before I bought the car.
What needs to change? The trans gear? Sorry for my ignorance here, but I would like to know how fast I am going, so I can abide by the law of course.
