with the 5.875 back spacing in the original post could be the correct wheel if the 6" rubs - you may be able to get away with rolling the fenders - maybe difficult to figure out wheel to fender clearance without the wheel - wider track is better handling - maybe you could borrow a wheel and give it a try..? I had a wider tire on the front of my fox - didn't rub on the control arm but the left front rubber side wall would touch the plastic inner fender slightly on tight turns....
