HZJ75 pickup breathers? Where?

[EsbenDenmark]

I know there is a breather tube on both the front and rear diff housing. I have extended these two hoses up to make sure no water gets in during river crossings.. But where else is there breathers on my truck? Gearbox? Transfer case?

The gearbox one comes out at the top of bellhousing and sits up against the back of engine. Nightmare to get to without removing The box
