1st of all, the transmission I have on my car is not a single speed, it's a three speed from an Overdrive ST. And also, the gears in the Diff. are alligned correctly. In addition, the last time I checked the forums were NOT for being sarcastic and unhelpful. I would be willing to bet you don't know the first thing about what I'm talking about, SenSeiRC. How old are you? 15?
