The six speed is also very heavy compaired to the 4, so watch your axle weights, I had to remove a six and fit a 4 years ago on a 0813 Hi-Ab lorry as the craine and box put the front axle over weight!!!!

Yes any cargo box, but the 6 box is longer than the 4 so you will need to change the prop, and a 6 speed might not give you that much more go as its not just the gear box it the diff as well. and if your cargo is only the 110bhp it wont will any speed records.
Have a look at you diff and see what ratio it is the plate is on the top near where the prop meets, if the plate is not there jack one side of the back axle up and count how many turns the prop does to the rotation of the wheels.
