Rotoflex pinbox install question

[riflegunbuilder]

Took my old broken Roto-Flex off last week, Installed the new one today. My mind has gone blank on the bolts closest to the camper, there is a piece of angle on each side; does the flat side of the angle point towards or away from the camper?

Looking into the pin box from the back side.

Thanks. I remembered not long after I posted that I could see the nuts from behind, so I remembered they looked like yours in your photo. Thank you.
