We need to know the info on the alternator. Is there a part number? Or what engine did the 2003 Mustang have in it? Is this the stock alternator out of that vehicle? As it sits, it looks like the only alternators that fit an 2003 Mustang 3.8L are from 01-03. So this would not fit your 1998.
Let me know this info and we can go from there. Thanks
