There's no room under there for a 5 speed. The transmission was built specifically to fit the Taurus/Sable, if you could somehow mount it there are so many other problems you're going to run into.
I still think the best choice for this project is the SHO transmission from a g1 or g2. It's actually made for the car, and things can be machined to bolt up. Bolting it on is the least of your worries.
