Here is what I have in mind for the D-rings and bed strips. My OEM strips are trashed after all these years and a very good friend just gifted me a set of stainless strips to use for the build. They should arrive about the time I am ready to install them if all goes well. The one good strip is more or less installed, just to get a better idea of how it will look, before I drill a bunch of holes in the floor. Keep in mint, the picture isn't upside down, the bed is.
The addition of the D-rings will also give a little drainage for the bed as well so I don't have to worry about water being held in the box.
