I installed fiberglass fender flares, a shelby racing apron (with the lip spoiler) a shelby hood scoop, and side scoops on my 66 coupe. This combo looks amazing and always turns heads. It can be purchased in pieces from Maier Racing located in Hayward, California.

I'll post some pics of my kit as soon as I figure out how
