1965 Mustang Producer

Ringbrothers’ 1965 Mustang “Producer” wins Goodguys 2012 Street Machine of the Year

Well known for their ability to transform Mustang’s into modern masterpieces, the Ringbrothers have set the bar even higher with Bowers ’65 Mustang. The body was widened an incredible four inches, highlighted by the custom BASF orange paint, and both the hood and roof are carbon-fiber – signature Ringbrothers touches. Under the hood is high compression Keith Craft-built 427 cubic inch stroker based on the 351 Windsor small block making 740 crank horsepower. The matte finish three-piece wheels designed by the Ringbrothers were built by Forgeline. Baer brakes, Afco shocks and a suspension consisting of front tubular A-arms and a Watts link set up in the rear give the car razor sharp handling. The car gets its name from Bowers’ Waynesburg, Pennsylvania based Producer Supply Company.
