What are these holes in trunk for? 67 Barracuda

Thanks Alan, that answers my question. Man, all that seam sealer for that little hole. Looks like the other hole was just left open. I think I have some body plugs that size, will just plug them.
Welding on the rear valance tonight then she goes on the rotiserie.
That was the end of the sealer, if you look (at my pictures) you can see the Sharpie outline of where the sealer was at along that seam.
