Looking to cut the fenders cause they have rust and I want to stuff big tires with little lift. My question is what do you do with the rear inner and outer quarter panels after you have cut them. Did you seal up the inner and outer panel, and if you did how did you do it? Or did you just leave the gap between the two and not worry about them rusting the truck from the inside out. Also does anyone know if Bushwacker flares cover up this gap??? Thanks.
