there probably was some in there originally but you don't need it - where the screws go through there is a "tower/spacer" on the upper ones - yes? 3 screw points? upper, lower and foot sill right?
Sorry Mike I was outside messing with it. Yes, I have the screws but the way it wedges in there and the kick plate holds it down, don't really need them. I just kinda thought I could make the car a little quieter with some insulation.
