The one on the right hand side of the picture gets pushed in between the floor pan and the rocker panel. I've got two of them on my 68 Dart....one on each side. Their position is basically in line with the middle of the door. The originals have that hook on the top. The reproduction clips don't. The reproduction clips kind of have a serrated edge that grabs the floor pan/rocker when tapped in place. You can see it in the attached picture.
