If i was in your situation (not that i have a zook, but i want one, and read the zuk section from time to time) I would do what christover suggested in the 32 thread you started.
Buy/make extended shackles. 40 - 50mm = roughly 20 - 25mm lift?
Move front diff foward.. 20 - 25mm? (easy, and can be undone, no welding needed)
Then, bash your guards/seams etc as much as possible (without destroying them)
Once youve got your axle centred in the wheel well (moved foward) and as much room as you can in the wheel well, extend your bumpstops to required length to limit uptravel and prevent rubbing.
From there, if you wanted to stuff the wheels right in, you would start looking at cutting guards.
Theres a thread on here, (canberrazook in members thread) where canberramav removed his flares, cut his outer edge of the body/guards into tabs, folded them under and riveted them back, and then fiberglassed and painted over it all, to open up the wheel wells alot more.

If it were my zook, (and wanted to fit 32 - 33" tyres) i would look at doing this, matching it with some wider offset wheels to clear the springs/inner guards, and attaching some wider/new flares over the cut guards to cover the wider stance with the bigger offset rims...
