My buddy came over and we finished the passenger seat bracket. We used 3"x3" angle made from mild steel. The steel is really strong. We used bolts that stuck out of the existing seat bracket because they were there for our use. The new Tom Motorsport Seats bolt directly onto those brackets and the stock sliders are used. The good thing about this design is that if you like you can replace the stock seats because the factory seat bracket is unchanged, only added on to.
