Ok, the 909 box, if I was to take one and try to fit it to a road car, what else would I need, are the props, mounts, flywheel/clutch the same as a STD cossie?

Which uprated box is best for say roughly £3k, Bara, Dome, Quaife, Fixit, Oppliger, 909, or any others I should be thinking of?

I was getting all embroiled in the noise and ratio issue but now I'm thinking screw it, just get the best box for my budget.
