How does the trunk divider install

Can't quite figure out how this goes in place? I have seen photos of 69's where it hangs on to the seat hook's! But there are no such hooks on my 64 Vert!
I do know now that at least it attaches from inside the well liner! Pic's are worth a bunch of word's! Thanks FABO

I can get you a pic of where the hooks are on my 65 dart sedan later today.
