I agree with TeeJay, you will have to use new hardware. When I replaced mine, I used a dremel tool and ground the heads off to remove the old flares. After removing the flares, I carefully drilled out the old riv-nuts. My stealership had replacement riv-nuts, but they were $4 each. If I remember correctly, you should only need 8 new ones. I opted to be creative and fished bolts through the access holes. It took a good bit of time and a lot of frustration, but I got it done. If I were to do it again, I would spend the $32 on the OE riv-nuts.
