HEY DoubleLoader. I'm a little slow understanding sometimes. Are you saying there's a 3.70 and 3.45 gear set avaliable that will bolt directly into our factory Crossfire rear housing? If so,the gears should also bolt up directly to a WaveTrax LSD thats made for out cars? Or were there machining modifications required? Or are we talking about slipping a different model cars rear end up under our car? I'm in hopes you have made a unique discovery. Thanks..Squirrel Crusher
