Any '76ish Ford 4x4s over there? (I assume yours is the same LH drop as US ones made after '79?) I put a '76 Ford F350 dana 44 front axle in my '84. (It's wider. I'm using the brakes off the Jeep and the Ford inner axle shafts)
That bolted in place of the original for 7" of front lift (because the axle is under the springs instead of on top of them) Then I had the flat top knuckles drilled for high steer (I have high steer arms from http://ottindustries.com
in Canada) and I'm using otherwise pretty much stock Jeep steering, etc.
In the rear, I have flipped the rear shackle and plan on using Riverbeast rear spring drop kit that uses the original spring, but moves everything down a few inches. (a pic of my rig in progress is under the "show'em" post)
