Yes you should be able to run the 33's, I will be hammering back the inner fenders on my SWB and drilling the spring perch to gain another inch and mount 34" LTB's with no rubbing. Just remember, big tires means things break. Heavy wide 33's will actually break things faster then the taller thinner LTB so drive her nicely and if you are locked, do not let a lifted tire hit the ground again under serious skinny pedal or you will pop an axle.
