You have several options:
Option 1
an '86-95 rear axle (from the IFS trucks and 4runners) will widen the rear stance by 3" total (1.5" per side). Superfly is selling one super cheap right now. It's a simple swap, although you'd want to put your 5.29 ARB third in that housing.
if you did that, you'd want to widen the front by 1.5" per side. you can do this with wheel spacers, or an IFS hub conversion ($$, but no spacers).
Option 2
You can run really deep dish offset wheels (2.0" backspacing). These are tough to find, and you'll either have to have them custom made for you, or get lucky and find some used ones.
Option 3
Or you can run wheel spacers, which isn't as bad as it sounds. Most yota guys use 1.5" wheel spacers.
Option 4
Did somebody say dana 60s?
