3 Point Retractable Seat Belt Kit features a quick release push-button buckle and is constructed of OE-quality herringbone webbing. Seat belt kits are a simple, direct bolt-in installation using the original seat belt mounting holes. Mounting hardware for the retractor to floor bracket and for the shoulder belt is included. Reuse existing hardware to mount the retractor and the buckle to the floor or purchase new bolts; see below. Federal regulations require seat belts in all trucks manufactured after July 1971.
