That's a mustang/crown vic style floor shifter.
Sure you can convert to that, I run one of those in my BII
You will need the shifter, the cable and a new park pawl in the transmission
Why? Because the column shifter cable approaches the transmission from the front, the car style floor shifter cable approaches the transmission from the rear so you have to change the pawl in the transmission so it faces down instead of up.
You will have to rig a mount for the shifter, and wire up your OD button and shifter lights to the interior light circuit.
I love my floor shifter!!
Is your 2000 Ex a V6 or V8? If its a v6 yo may have to do some custom work to the parking pawl to get it to work with the new cable and rear approach. For the v8 trans the parts are available from Ford.
