Iceland Offroad suggests having a friend or two hold the flare on the Jeep where you want it while you mark where the holes need to be drilled with a right-angle pick. If, like us, you have no friends, we suggest locating the rear half first. Align it with the door opening and mark the forward-most bolt, then drill that hole. Work your way towards the rear of the Jeep marking and drilling one hole at a time. Bear in mind that the top of the flare does not ride parallel with the body line when finished. Once the rear half of the flare is located, the front half is easy. Then by simply cutting the pinch seam, we were able to push the inner fender up to the body and weld it back together. If it was cut any further, a new panel would need to be made for the inner fender.
