Maybe someone removed the hitch, that would take the hooks with it.
It would also increase the departure angle. My hitch has the step over it and you might just make it out in my avatar, the hooks are a little lower than the cover.
The four bolts that hold the hitch on, or at least the holes should be under there.
You might have to create your own set.
I don't suppose someone wants to take a photo of where they are for me? It's still fairly muddy under there I don't suppose you unbolt the towing eyes to fit a towbar do you? I think a previous owner had a towbar on it.
mine was until the other day bolted on to where the tow bar mounting bolts are, i say was becucause it is now a rather compressed shape after bending the tow bar on a rather large stone, if the previous owner has fitted/removed a tow bar that would explain why you dont have them as after looking at another rav in a car park that one had two on it.
