Sill plate installation

Well, you can line up the sill top holes if you have them, then drill your holes front and back. All of those holes are just drilled into the rocker sill top.
I have seen sill plate screw kits, some with longer screws and then some with just the smaller ones. I have new sill plates so, I will definitely be taking your advice and restoring the hole into the floor/sill area . Thanks again.
