My 98 SE has skirts. When I replaced the front fender i discovered that they are held on with clips that were spot welded to the fender and the rockers along with a plastic pushpin connector in the wheelwell. The new fender didn't have the clips so I just used a stainless sheet metal screw under the jack cover towards the front of the hole with a rust preventative in the hole. I just looked at it (2yrs later) and didn't find any problems. I don't have any idea where you could get the clips.
