JEGS front caliper brackets are for use in racing applications and street rods. These brackets fit Pinto or Mustang II Spindles (1974-'80 Pinto or 1974-'78 Mustang II) and use GM Metric calipers (front calipers from 1978-'88 GM Mid-Size RWD cars) & Granada style rotors/hubs (1975-'80 Ford Granada or HP Granada style rotors). This combination of parts converts the brake system to 11" rotors and 5 x 4.5" bolt pattern wheels (both sold separately). 1 per pkg. Made in USA.
