Not sure what manufacturer the dealer installed, but the TRWs I got at Part Source for $50 + Tax they also come with a life time warrenty, I took em over the Ford's that had a one year warrenty and cost $60 + tax.
Look on the back on your key fob, TRW makes everything. They do everything automotive.

Curious to know if anyone has pictures of the OEM end links on the SVT.
