Bit of a thread resurrection!

I`m looking at options because I`m still on a 2wd plenum. I am very space restricted as the engine is in a Westfield. Hart plenum just won`t fit.

The top chassis rail had to be notched to get the throttle body/elbow to fit as it is. Do the other Ford options like 4x4 or ST fit within the same footprint/dimensions?
