I have an 80 that has about 2 inches of torsion/spring lift and a 3 inch body lift and 31x10.5s still rubbed the fenders between the door and the wheel. I'd say just a little bit of trimming though would get you there with the same lift combo. It depends a lot on the wheel offset though, if they stick out farther they rub worse on the fender, but you gotta have them out far enough to clear the frame. A narrow 31 like a 9.50 might help.
