If you're going to remove seats, might as well take out the passenger's altogether too. I'm not sure if the tunnel was high enough to let the bumper sit normal, I know when it was turned face down, the sides hit the top of the decklid. If it will fit normal, you can probably sandwich the front [in front of] the rear & slide them towards the front of the car w/ the seats removed.
...or get the windstar
