The Corbeau Ford Mustang Lowered seat brackets are manufactured to be a direct bolt in to the 1978-1998 Ford Mustang and are 1 inch lower than our standard 78-98 Ford Mustang seat brackets. Direct bolt in means your bracket will bolt to the existing bolt holes in your floor board with little to no modifications. Corbeau Ford seat brackets are powder coated in a black matte finish and include Double Locking Sliders.
