The suggestion is that there is a difference between a RWD and 4x4 in that the 4x4 has a larger transmission tunnel to accommodate the front prop-shaft and cut outs in the front chassis legs to take the front driveshafts.

Therefore I assume I'll be needing a 4x4 chassis regardless of manufacture date, the question is which one? Aside from the wheelbase, are Sierra XR4x4, Sapphire RS Cosworth and Escort RS Cosworth chassis' fundamentally the same remembering I want to build it up to Escort WRC spec?

I also dug this up while searching the net for more build info, does anyone know anything about this car and where I might be able to find some more info?
