    Would love to see the local cops trying to decide why it's illegal

    If you've got live axle front end, you need live axle rear end. Independent would be fine for a long arm independent front end...

    2 live diffs with rear cover plates

    get busy on CAD and design a new back plate to carry a second pinion to create and output from the crown wheel.

    then you have a 1:1 reversed output out the back of the middle diff.

    flip the second diff to correct the drive, and put a sliding prop shaft between them.

    Lower trailing arms on each diff with a panhard rod.

    bleed the brakes, bolt on the wheels and sort out the body work...

    (or at least, the South African version had 6 Wheel drive, the Germans could only manage 2 wheel drive )

    we actually ran a chain to the front axle too as it needed to make it's way across the dunes.

    I have to say, it did better than a Porra in a Fortuner!

    Best is to keep both rear axles independent. Run direct off your current TC into another that has been "inverted" and the low range removed to simply split the drive to the rear. Maybe look at the rear diff with an offset pumpkin to line up better to your "splitter", but not crucial due to the length of your second propshaft, and the route it is going to take to. Run the second propshaft over the the center diff with a carrier bearing mounted direct to the center diff.
    Center diff you do NO steering, but the rear diff you can steer at a ratio to the front wheels to enable the vehicle to pivot around the center wheels a little. You can do this by taking a pushrod setup direct off your steering knuckle to the steering knuckle on the rear diff. 8 wheel trucks "push" the second axle this way, or you can get fancy with an hydraulic setup.

    Biggest challenge I see is keeping the vehicle length reasonable, and then, how is the weight going to line up legally with your registration/license docs.

    the problem with running a prop over the centre axle, is that you lose travel on the rear diffs - the centre one can't go up into the rear one's prop, and the rear diff can't drop down as the prop will hit the centre diff....

    or you have to lift the motors and boxes, tilt the diff so the pinion is up and run a 90 degree drive into it. but then you've got a high COG with low clearance...

    Eish.

    That prop would need more than a centre bearing. It would need joints each side of a fixed bearing and 2 sliders.

    It also starts to get kind of long with the extra box and propshaft in between...

    but yes, it would work....

    The rear axle cannot possibly have enough range of motion to cause the over-the-top prop from the middle axle transfer case to engage with anything

    The Australian Perentie Defenders with the Foley 4x4 system work exactly like this and have had no issues.

    no, that is not as Peter drew/described.

    that adaptor is bolted to the front of the middle diff and moves up and down with that diff.

    BfreeSani is David. But you can call him Arthur or Peter if you wish.

    If you are anything like those kids of mine, you need very little convincing . Thats my daughter who just got back from the mines, and had a tough morning with the guys out there wanting all kinds of stuff she knows nothing about.
