Gary - how are the front clips different between the Mk I and Mk II cars?

MK II front clips have raised "wings" over the wheels, they are about 1.75" inches taller tan the MK I model. Also all MK IIs have the single large radiator air exit as also used on the late MK I cars (i.e. "Gulf" style) where early MK Is used the twin triangular outlets and a MK II does not have the center NACA duct of a MK I nose. The center spider and doors are identical in shape between the models. I suspect there is no difference in "downforce" between the MK I and MK II noses.
