From the 1970 Ford Mustang Data brochure:
The BOSS 302 Mustang Sportsroof is powered by a 302-c.i.d. F.I.A. formula (5-litre) engine aimed at the International Sedan Racing Class and the formula-oriented sportsman driver, and offers many unique features as well as an array of special options not likely to be seen on any other "street" machine. Its curb weight distribution balances out at 56/44 and its handling is further enhanced by a functional front spoiler, wide F60x15 fiberglass-belted tires, quick ratio steering, and a rear sway bar.
Exterior features include a non-glare racing black hood, rear deck and back panel plus a unique side stripe combined with your choice of eleven colors including Grabber Blue, Grabber Orange, and Grabber Green.
