Thanks everyone for their replies. I banged out the front pinch welds the other day...a lot easier to do than I expected. I ended up using Gorllia Tape and Truck Undercoating to patch up the wheel well liner which came out pretty good.
NEXT QUESTION: Is it necessary to do the rear pinch weld mod with my potential setup? (OME HD Lift, 17x7.5 MOAB Wheels, 255/75/17 tires, 1.5" Spacers) If it helps, I am not looking to get into serious offroading where I am looking for full articulation
