I am in the middle of a Toyota axle swap on my 82 sj410, I'm just running 33" tires but I think you would have room for 35's with the yota diffs and a yj spring over axle setup, if not you could trim the fenders a bit or just get 2" lifted yj springs and that should give you lots of room for 35's if you don't want to trim the fenders.
