Looks similar to what I'm working on here.....
Nissan GU 4.8 petrol 3.54ish ratio with ARB locker running 24spline side gears?

4.11:1 over here I think.

3.9 in lots of mavericks and petrol auto, 4.6 in 2.8 diesels, 4.1 in most all else
Yes - Patrol GQ
Used the GQ as opposed to the GU as it has basically the same King/Swivel Pin inclination as the Rover - the GU doesn't.
Right now it is;
Nissan axle casing, nissan diff and nissan inner axles - all standard parts (although this diff has an ARB )
Then Rover swivel housing, stubs, bearings, hub, brakes etc, then Rover CV Bell and outer drive member/axle (using Range Rover 10 spline just cause I have them laying about, will work with 24 spline as well) - all standard parts.
To link the outer Rover CV Bell to the Nissan inner axle it has a Toyota CV star.
To bolt her up under a Rover, other than a modified Panhard rod and drive shaft mod., it needs only 3 different 'non-wearing' parts with a total part count of 6. Oh then mounting of the shocks - I plan to put air springs on this so most likely keeping the standard Nissan locations.
To keep things even easier, it looks like with some machining of the stub axles, a bush and a new drive member splined to the Nissan outer axle that the standard Nissan full axle can be used.
Can some one confirm that GU CV's are stronger than GQ? And that they are interchangeable? If this is the case then this will be the way to go.
Plan is to put it under the Isuzu 110. Really only started out wanting to put a turbo on my motor - so I could smoke all 4 wheels like Dougal canFigured I would need a stronger drive train first. Gearbox - check. Front axle - on its way. Then might get around to finishing the turbo...... Lucky Rovers last for years!
Oh plus the Patrol Axle tubes are 90mm dia. compared to 80mm of the Rover so should help prevent some bending with the Isuzu above it.
Can get;
3.54
3.9
4.11
4.375
4.63
4.88
For the Patrols.
Nope will be easier to just swap the front.
I am happy with the strength of my rear salisbury.
Might even do a second axle and get rid of the hi-pinion 4.88 Toyo Bunderra diff in the front of my 90 and leave the hilux in the rear.

So the nissan inner axles are 30/27 spline?
What does the track end up at?
The radius arms are wider-spaced on a nissan aren't they?
As for GQ vs GU - sounds like GU are slightly larger and the inner spline is different:
GU cvs are apparently a lot stronger though.inner splines are different as its a different series joint GU is a 109lac NTN ,GQ is a 100ac NTN so you would have to use GU axles which are to long for your housing and as already said they wont fit in your swivel housing anyway. The only way to use GU cvs in a GQ is to fit the whole diff
Yes
Not 100% sure yet. Standard Patrol is slightly wider, but Patrol swivel housing are slightly wider than the rover. Instead of measuring each component and calculating, I figured I will just build it all up and when complete measure it. Saves on error stack (what I am not perfect?).
From my measurements the Rover is 21mm wider - hardly worth worrying about.
Hmm I thought with a little mod, they would fit
ARB Locker Application chart says same Locker, same axles spline and diameter for the GQ/GU.....

The splines in the CV star.
So even if you could squeeze the GU CVs in, you would still need custom inner axles as the GU inners are too long.pic of a GU CV beside a GQ CV ...
the axle of the GQ is smaller than the GU and it just spins inside the GU's cv joint. the outer spline count and diameter is the same 32mm 31 spline so free wheeling hubs should interchange.
The GQ C.V. is marked ... "birfield-NTN 100 AC"
The Gq axles have a 29mm 27 spline outer end 43mm long and a 32mm 31 spline inner end 50mm long.
The short axle is 416mm long and the long axle is 916mm long.
