well, the darn thing is out

There is a panel you are missing ties into the top panel you have in place, (where the starter button is affixed). The lower section fills the remainder of the hole sans the transmission top cover. Essentially there are three pieces in total for the center. With the three pieces removed, it made engine and transmission access easy. This also allows the body to be removed without removing the steering wheel. I'll look around to see if there are any reproductions or descent used ones are available.

There is also a cover that covers the passenger floor toe board. This one allows access to the heater core if equiped from the top side. I'll get you some pictures early in the AM.
