I also get rubbing inside the fenders on the surface that would be the floor or firewall. I use 32x11.50s, so I am not surprised if yoru 33s rub there.
You can stop the rubbing on the springs by either adjusting the Steering Stop Bolts, or if they adjust so far they fall out (as mine did), then you can replace them with longer bolts.
The stop bolt that keeps the right side tire from rubbing on the spring is on the left steering knuckle, and vice versa.
Well, you can add a body lift, this will help alot.
