Thanks for the info Diana 
From the photo below I can see the difference in the FC exhaust manifold and pipe. I can also see the empty space where the radiator fan would normally sit.
What do you mean by a bonneted control box?
Hi Tommy
I overlooked this post. In the image, it appears to be missing the pulley on the water pump. As opposed to most Land Rovers the F/C has a heavy, cast, quite long cylindrical pulley that is a press fit onto the water pump shaft. The flat end of this pulley is the same size as as the round flange of the prop shaft and is drilled and tapped to accept the prop shaft bolts.
On a usual Land Rover 6cyl, there is 1" adapter plate to change from the 3 litre style water pump to the Land Rover pump, this pushes the pump 1" forward and the F/C pulley won't fit (it may also make the prop shaft too long, but I havent fitted one up to test.) You can't fit the 3 litre waterpump and F/C pulley to a normal Land Rover 6 cyl without also changing the head because the coolant bypass ports are in different places.
Bonneted controlIn some of the OEM Land Rover manuals and handbooks they refer to the majority of Land Rovers as
bonneted control to differentiate them from
forward control Land Rovers. It makes it hard when Rover Co used the term
regular to describe the 88" when they described the 109" as
long i.e. Regular and Long models.
In short the term
bonneted control would be
normal control in the parlance of other truck manufacturers.
