Rock Slide Engineering - Receiver Hitch Step Slider

This item comes with no instructions and no documentation. It is clear that you insert it into your hitch receiver. But then it includes a strange bracket that only fits on one side.

On the Bronco Raptor, the bottom edges that curve up run into some bolts and it does not cleanly insert up to the predrilled holes.

It is very heavy duty steel and seems to be well-built, but it is not yet clear to me that it is actually compatible with the Bronco Raptor.
