So here's how it went... Oh, and I should point out I did this when the car was cold. I got up close and personal with the exhaust system at times so would have been a bit unpleasant if the car had been run first.
Original fitting and hose

Removed the clip holding the hose and disconnected it.

Here's a comparison of the original fitting and the replacement quick connect fitting

This is the chassis cross-member that the other end of the original hose terminated into. There's a similar barbed fitting screwed in there too. I removed it but it could simply be left in place.

The kit came with 2x straight and 2x angled fittings for replacing the ones on the diffs, the gearbox and the transfer case. I think the angled ones are generally intended to fit to the gearbox and transfer but I ended up going with an angled connector on the rear diff because a) it allowed me to keep the hose well away from the exhaust pipe and b) there's little chance I'll be able to get to the transfer or gearbox ones to replace them. I decided to route the breather hose with the vacuum lines for the diff locker (marked) since they end up in the engine bay next to the other breather hoses.

The vacuum lines become slack rubber hoses forward of the rear axle to cope with suspension movement. I simply followed them with the breather hose leaving a similar amount of slack. The flex conduit was simply to stop any friction damage to the poly hose. If it were a rubber hose I would have been happy to leave it unshielded.

After that the vacuum lines follow another chassis cross-member to the other side of the car. I decided to go above that cross-member to keep it away from the exhaust pipe on the passenger side. There's a foil insulated pipe that crosses in the same place so I just used that as an extra heat shield.

That get's the pipe to the passenger side chassis rail. As luck would have it, there's some plastic clips that carry the metal vacuum lines down the passenger side and there's a spare slot. I used them but cable tied to be sure - plastic clips break eventually.

Just behind the front wheel arch the exhaust pipe gets quite close to the vacuum lines. I decided to stay well clear and crossed the top of the chassis where there is a foam-insulated pipe for the A/C system.

I just followed the forward end of that to inside the wheel arch and up into the back of the engine bay (pic does not show final position of pipe). This came up right in front of the firewall and I just brought it up leaving a little bit of slack and fixed the filter end at the top near the rear of the engine.

The only good thing about an 80 series is..... the front end?? Wrong!!, the Engine?? Wrong!! the Full Time 4WD system?? Wrong!! Its the NissanPatrol.com.au stubby holder fitted over the transfer lever.

No worries
I'll add to this when I do the other ones, but they are a much simpler job since I'll be utilising most of the existing pipework.

Do people modify the gearbox and tranny breathers, I've not looked, but read that they are quite awkward to get to.
I was just thinking of buying some tube for my rear diff and running it up into the body rear so it can vent near that air inlet by the rear window. But I've not done any work at looking into that to see if it's possible.

Gearbox and Transfer case are not that hard. Their breathers are joined together. I had to go to Pirtek and get a adapter from memory, so i can adapt the metal breather lines into the plastic breather lines. All 4 of mine go into the engine bay.

So what happens to them on the other side of there?
Yeah, does anyone know what happens to the tubes on the other side ???????
I finally got around to looking at this yesterday and thought, if they go up a little bit higher they'll already be at about the height they'd be if I put them on the top of the firewall.
I'm wondering if there's much advantage to extending these from group of breathers???
The rear breather is a different story.
