Those Duralast from Auto Zone don't say that they fit the SVT, so be careful.
I've found that when they say something fits, it usually dosen't, passenger side motor mount for instance does not fit.
Advance Auto Parts specifically says that these 2 axles fit our SVT's:
Driver side...Remanufactured $60
Passenger side... New... $100 these are in and out of stock, so you have to keep checking the web site for availability.
