What bolts on here?

What is around the column inside passenger compartment now? Looks like somethings there now? Column has to come back out to put seal and steel plate on. Or maybe if steering wheel is off can slip over that end?
Looks like I have a 3 bolt plate with a two bolt plate on top of that one on the inside of firewall. Same as in pics posted by Oldmanmopar. I will put the white foam gasket on the inside.
