This Complete kit included everything needed for either a 1964-1965 K code 289 HiPo Mustang or 65 and Early 66 Shelby GT350's. This design is much more stronger than factory 64-66 Mustang Engine Mounts which fail quickly when exposed to excessive Torque and Horsepower. These are exact Copies of the Originals. Includes Lower Cast Frame Brackets with Part Numbers, Intermediate Brackets, Upper Engine Brackets, Main Rubber Mounts, Donut Rubber Isolators and all necessary correct hardware for a trouble free Installation. Originally these Brackets were raw and quickly surface rusted, ours are painted a natural steel color so it will look like new for many years.
