here's the ideas I had floating around in my head for the front end:
get the fullsize nissan straight axle from an aussie Patrol. then switch to titan rear axles to get standard nissan lug pattern to match. brakes should be large enough since the patrol is fullsized
drop in rubicon med-wide track from 2007 jeep wrangler..ditch or convert rear axle to have matching jeep lug pattern.
figure out how to use a bigger IFS diff with some kind of custom axleshafts made to fit.
buy a 4runner or 'gasp' you know what.
ON EDIT: scratch the patrol..it has a passenger side drop on the pumpkin.
it's fun to look at anyways:
