You can buy the Steeda from SPmotorsports, your better off looking on E-bay tho.
For the steeda its actually the short throw for the focus, 00-02 years to be exact. You will need an adapter plate from Scottd60 to make the shifter work (due to it being a true shifter and changing the fulcrum point)
The Steeda is amazing tho, i installed mine last week and i cant get enough of it, its probably the best mod ive done, it totally makes the car feel like a sports car.
