Some of those holes were used for the clips which hold in the internal firewall insulation pad. When I did this, I reused that pad and simply applied it over the top of the sound deadening stuff. Those holes that weren't needed I covered with plugs just like Tim did. I got them at TruValue hardware store in their Hillman parts section and think I may have paid $4 for all of them. The ones I got were black plastic.
