Before you go swapping Alternators, I believe there are 2 questions that need answering:-
1). The stock 94/95 SC Alternator, as you say is rated at 110a, whereas the normal T-bird is 130a?
2). Also on the '94/95 SC ,if you install an aftermarket alum pulley you need an additional spacer washer - this would indicate that the alignment on these Alternators is different from prior years.
Hopefully someone will have those answers.
