I bought this air dam 10 years ago on ebay for $75, the ad said it was for a 73 to 76 duster/dart but from the shape of it I thought it would work on my 72 duster. I did have to recess the center of the air dam to clear my license plate bump on the bumper but it turned out pretty nice I think. I can't tell you how many people ask where I got it or who made it, there were no markings or part numbers on it. I think $300 for yours is a good deal!
