Missing Headlamp Cover

Yes, the right headlamp cover is gone... along with the $70 it will take to replace it. Halfway through the race I was battling a Porsche 911 for 8th place overall, and he decided not to let me past even though I was a few tenths quicker. He blocked me all over the track for two laps (4 miles) before I finally got tired of the routine and didn't give way. His left rear came over into my right front, creasing sheet metal and shattering the headlamp cover. We both continued. My ignition module died two laps later, ending my race. The Porsche driver ended up in a post-race conference with the series director.
