It has a U shaped piece of metal that holds it in. There is a spot for a small bolt above it. If you are behind it, it goes in on the left side towards the back. I can't take a picture for you right now, but you can do it.
just stick it in there, slide the plate over it, put the bolt in.
I love little baby ducks, old pick-up trucks, slow-moving trains, and rain
I love little country streams, sleep without dreams, sunday school in may,
And I love you too
