The actual solution is very simple.

I made some progress today - for the first time.  It took 4 hours to get the body stable and get the body cart out from under the body.

The pan is bolted to the body at the rear 8 bolt holes and the front four.  None of the side bolt holes are attached but that's of no consequence here.  I'm not going to drive the car in this condition...I just need to keep the two together until I take it apart to modify the holes to get the entire floor secured properly.  The mismatched rear seat kick panel situation needs to be rectified along with welding in the correct location for seat belt brackets-two things that are going to get done with the 'fix' for the floor pan holes.

I'm going to try to get the front end back on tires tomorrow to stabilize the body and get parts off of the table.  Getting the rear end on and on tires is going to be a far larger challenge.  But that's for later.
