At least on the first gen if you don’t have the factory tow bar you have a crash bar that bolts into the same location. It’s tied to the rear body with a few bolts each, and the tow bar also extends back into the unibody for extra strengthJust FYI for those considering this, I think you will need the factory (or Draw Tite version) trailer hitch for these to bolt to. Without it, there is a bumper beam that extends outward beyond the inner edges of those 4-bolt flanges that hold the hitch/bumper beam/tow hooks in place. If you don't have the factory-style hitch, I believe the main portion of the bumper beam that extends past those mounting points will interfere with the tow hooks.....seems like there was something about two objects not being able to occupy the same space at the same time.
