It might be easier to take all of the 4x4 parts from an existing vehicle that is already set up for road use with permenant 4x4, or at least the centre diff arrangement.
I have got in contact with the company that makes those transfere boxes today and they can build one with a slipper diff inside, they are getting back to me with the exact spec, so do most 4wd cars use a slipper diff?
How does the slipper diff actually work?
If a centre diff was an open diff would the front 2 wheels just spin if they were on an ice patch etc?
