Sorry, but I'm seeing this message for the first time. You may have already gotten your answer, tho. It wasn't difficult to replace the badges at all. You need a heat gun or hair dryer/blower, a straight edge and plastic wedges or paint scrapers.
I had a 3" Performance Accessories Body Lift on the truck with 315/70/17 BFG's on it first and then 315/70/17 Mickey Thompson MTZ's on it later. The body lift was the most economical way to lift the truck and then I cranked the torsion bars a little to level it out. The key to the 315's fitting was using the stock Fx4 wheels.
