The Corbeau Nissan/Datsun 260Z seat brackets are manufactured to be a direct bolt in to the 1974-1975 Nissan/Datsun 260Z. Direct bolt in means your bracket will bolt to the existing bolt holes in your floor board with little to no modifications. Corbeau Nissan/Datsun seat brackets are powder coated in a black matte finish and include Double Locking Sliders.
