I have a 1993 SC2 and just replaced the alternator. It is located below the power steering pump and has to be changed from underneath. First and remove the negative battery cable then jack up the front end and support the car securely with jack stands. Remove the passenger side tire. You will also have to remove the plastic inner fender well. Once removed the alternator not too hard to replace. It is secured with two bolts. Mine took me 45min. hope this helps
