If your A-Body was originally equipped with a bench seat, you'll need to install the factory-style inner bucket seat floor brackets before using these mounts.
This not only provides the correct mounting points but also helps meet NHRA requirements, which do not allow racing seats to be bolted directly to the sheet-metal floor pan.
