Your car sits much higher in the rear than mine.Must be the bakkie leaves.
Mine still has the old GX sedan springs in it and I can feel that they are on the soft side.
Just something interesting, if you would drop it lower, will the tyres rub?
I am trying to figure out why mine is rubbing when going through a dip.As you know the diff is a little off centre but I think the soft, old springs are also a reason for that. Currently I am running no spare wheel or anything in the rear otherwise it will rub constantly when going through small dips.

Had 2 mechanics look at the diff and the only conclusion they came to is that it is a factory error on mine as the collars that the U bolts go around is welded to the diff by the factory.

It's the tramps rods that jack it up like that. In later pictures you'll see that it sits lower in the rear, because I adjusted the a little softer. Or it could just be weight transfer to the rear. Yes, it does rub, but strangely more on the right than the left, but that might also only be because my backside is a bit wide and it puts more weight on that side...

square lights.... you fit them off a 1400 ute?
