99gatorbird

I just bought some TA ground effects from a 2001 TA. And i have a 99 v6 with no ground effects. I noticed that the TA piece has clips that would attach into the top of the rocker panel. I would assume that the body shop would have to drill holes in my rocker panel? Is this an easy mod? Right now i have only the passenger side. I have a few dents in my rocker panel will this make the mod harder? Should i just go with the wings west side skirts? I might sell the TA GFX if anyone needs it? Hit me back. Thanks
