Lance, My DeLorean came from its previous owner with a CD jewel case wedged between the windshield drain and the fuel pump boot since the original boot cover had shrunk to almost nothing. At the time I had not owned the car for very long when someone at a DeLorean car show spotted the jewel case. It was quite a laugh for everyone. The main problem with having a deflection shield is that it can clog the drain hole should leaves find their way in there. IMHO, I think that a properly installed fuel pump boot cover alone is enough to keep water out. Walt Tampa, FL
