We just changed the power steering pump on our '00 LTC. The pump we bought from Advanced Auto Parts looked exactly the same except for where the little solenoid screws into. The one from Advanced was too small. I brought it to a different Advanced and they claim that was the right part. So, before anyone goes crazy or buys one directly from Ford, Auto Zone (ack!)'s was the right one. It was too late at night to check Carquest or NAPA (and the O'Reillys was farther away than I wanted to go). Just wanted to post this in case anyone else had the same problem. Also, to take the pulley off you should use the screw type, not the 3 pronged clamp type.
