Hello, does anyone happen to know the size of the bolt that anchors the two rear seat belt receivers to the rear floor? I'm deleting the rear seatbelts and want to plug the holes with new fasteners. The shoulder harness into the roll bar is 7/16 X 1.25 but the receivers to the floor and the two retractors at the rear wheel wells adjacent to the rear seat latch brackets are larger holes. Hoping someone here has the facts before I start the process of elimination.
