Our bumper will bolt right onto a 392 hemi powered JL there would be no frame mods needed . The front aluminum plate does bolt onto the bumper so you could coat it or plate it to work as an accent panel . As far as the fog lights it depends on the lighting option you have from Jeep . Jeep uses 4 different style fog lights and only 1 will be a direct bolt in option which would be if you had plastic bumpers and the led lighting package .
