How is the plastic rocker panel cover on the 89 Alfa Quadrifoglio held on? A molded strip of black plastic -it has screw points at the front (back of front wheel well) and back (front of rear wheel well) but what about the middle area? Mine is loose on the driver side and PO used some adhesive to hold it on. Needless to say it has come loose and is an eye sore to look at. I would like to reinstall it properly and the passenger side is glued on with something...
