Sorry, I'm not sure what others have the same alternator as the SC. I do recall that if you want to keep changing it out a bunch, go with some aftermarket replacement. I chose to go with rebuilt one from Ford for about 170 bucks. Since the first one lasted me a little over 10 years, I'm hoping this one does too. I have a stereo system that's pulling quite a few amps (which should decrease the life of the alternator). Five years running but WAY less miles. (not my daily driver) Good luck!
