All the pop rivet holes were reamed to take #6 screws to allow for all the seat floors to be removable. Click Bond nutplates were used and the passenger seat belt attachment lugs were installed using nutplates and screws; this allows for the floor to be fitted over them when the screws are backed off. The Seat Belt Attach Lugs were widened slightly to allow the Hooker Harness Lugs to fit. The gap in the seat floor is too small to fit over the widened lugs unless the Attach Lugs are loosened off.
