That looks like a universal aftermarket replacement switch. No provision for the twist lock.

Okay Thanks..I'm going to order a new switch..The one on the car works flawless BUT I want the bezel on it

To make it factory correct, you will need the correct FoMoCo switch and lock with key.  None of the aftermarket switch can be used.  You will also need to repair the wiring on the back of the switch.  
Ford wires have rings that go over studs and are held with nuts.  Who knows what was done to install the universal switch.  (Maybe they didn’t cut the wires? Or damage them much). 

When your car was new a single key worked the doors and the ignition.  Your keys don’t match now, but perhaps you can find a set that includes the locks for the doors and the ignition?
