Also, as to body work differences, isn't it just a matter of undoing the dzus fasteners, fitting the new bodywork and you are off? Certainly, some of the venting may vary, but then you replumb the vents, right? Doesn't seem difficult to me to do retrofit. What am I missing?

Acutally both Prodrive and Rafffanelli are running bored and stroked 550 motors bringing them up to 6.0 liter dispalcements. Robert

I don't know for sure and I could be completely wrong but I think they are two very different racing cars.
The engine is different for instance (the base is the same but they are prepared by different people, even though they have the same 6-litre displacement) and its body styling is different (again, same base but different guys at different windtunels).
I think they only share componnets like the chassis (even though prepared in a different way), suspension (different geometries, i suppose) and gearbox (I'm not that sure about this one. Please correct me if I'm wrong).

Again, this is only my oppinion and could be (I ought to say, "it is") completely wrong.
