Hello: On the bottom of the floor boards of my 1969 01D camaro, approx. in the middle of the door, close to the rocker pannel, is a welded on piece that forms a platform approx 1/8" off floor boards. It is about 1/2" wide and 3/4" long and has a hole in it for a screw. There is one on each side of the car. They would seem to be for a clip to hold the fuel line on the one side and the brake line on the other. Does anyone have a picture of the clip used in this application. As always, I appreciate the help.
