I have a 1987 rs convertible and I have 87 z24 ground effects was wondering if someone could tell me the best method to install these? It appears that the z24 must have had clips or something that attached them because there are recessed pockets in the ground effects. Was considering the universal molding clips that have the perforations in them and inserting into pockets then bolting them on the car. Surely someone else has done this install and can shed some light on this. Any help would be appreciated
