Help Identify this Spoiler

Yes a T/A, It had an unbelievable story... it was 1 of 3 that were used by a Sherri f department... there was enough holes in the dash and sheet metal for radio's and custom weird brackets in the trunk... a friend had to have it and struck a deal.

Thanks for the input, my Bro's Orange and friends Purple AAR are beautiful stock rides. I was just wondering about the notch, thanks.
