they can fit, have seen them once before.
stock rims arent wide enough.
joshy ran 35x13.5s i think they were with a 2 + 2 lift.
you'll need to do a bit of guard work, how much? who knows til you fit them.
a few guys have run 35's before, bit slow off the mark but aparantly not un-drivable.
you wont need reduction gears that only changes when in 4L, but changing to higher diff ratios would bring the final drive back to around stock.
i dont know of anyone running a 3" body lift, 2 inch is an easy mod but 3" would cause a few headaches.
and as for rim offset, the more negative you go the more guardwork you will have to do.
you'd want to try and go with a postitive 20 or a 0 offset id think.
