Photos of Gearbox and front diff internals needed

[MacHooDotSE]

I'm looking for detailed photos (or a cutaway drawing) of the transmission (gearbox+central and front differentials).

What I specifically need is pictures of the central diff and how it is connected to the VC, the front diff and the axle going through the gearbox (to the real diff).

I have been looking everywhere, been talking to Ricardo Ltd (they bought FF who developed the transmission) and Quaife but visual info about the centre diff are still missing.

Please, can anyone help?
