Ok, I have done a body lift against what I wanted to do but....
The steering shaft from the body to the Prado box would not clear the engine mounts without it.
The steering shaft has been completed and is the Prado end knuckle mated to the Pajero shaft - just bored out the UJ on the toyo end and then put a new joint it - so simple.
The High pinion diff hits the sump of the V8 at full compression, and the motor is as high as I can get it with the engine mounts in place.
To combat this I will just pack the bump stops for now. The Prado's diff is more centered than a Hilux one which would be fine, as would a low pinion one but then all the steering would need changed.
The other option would have been to make completely new engine mounts for the chassis and engine to lift the motor and avoid the steering shaft issues by a different mount on the chassis. As it is the motor sits very low which is good.

The gearbox crossmember is made and in place, it is flat and is 10mm plate.
