4.10s with 30" tire??

What modifications are you going to accomplish to put 30" tires on it? I've owned a few A-bodies, but I haven't seen one that will fit a 30" tire without radiusing the wheel wells. 29.5" if you move the rear back, but never 30" without some rubbing of the tire on one of the fender lips. Someone please correct me if I'm wrong.
