Outer Limits 4x4 Board

Hey guys,
Quick question. Fitting a 2nd hand genuine toyota tow hitch to a 76 series. Each side has a pair of triangle(ish) shaped steel plates.

Where do they go? One on the outside and the other inside the rail, both on the outside or something else again?

Pic in my best MSpaint to show what I'm talking about, not to scale. It shows approximatly what you would see looking down the inside of the LHS chassis rail from the back.

can't help but ask, does it have to use those left hand thread bolts? must be hard to source
