I'm looking for the fin the runs front-to-back down the center of the hood. Apparently some Rivieras had a flat piece of trim there, but I need a replacement for my fin, which rises vertically above the hood, starting ~1/4" high near the back of the hood, and peaking at ~1.5" near the front of the hood where it goes over the crest. The front snapped off of mine when I rear-ended an SUV -- stuck into the guy's spare tire on the rear door. Bummer. Thanks!
