Removing the rear floor on a 2001 X-9

Does anyone know how to remove the floor behind the engine compartment, on a 2001 X-9? I have the complete engine cover off the floor, but have never had the floor up.

I dont see any screws or pins with a mirror and flashlight from the engine side, and the gas tank butts up tight and would have to be pulled from the stern.

Damned steering cable is frozen...
