On the rear section of the floor pan just below the rear seat there are the two reinforcement plates that the seat belts bolt to. There is a small captured nut on the drivers side that I believe one of the brake line clips bolts to from the outside. Were the original floors dimpled to allow room for this nut and bolt or was there a hole stamped in this location? I am at the point of welding the originals onto an aftermarket one piece floor and want to duplicate how the factory did it. Anybody have an original floor car they can look at to tell me what was original? The nut and bolt are shown on the pics.
