F355 alternator cross reference number?

My alternator died (again).

Does anyone have the Nippondenso (a.k.a Denso) number so as to be able to cross reference the alternator on a '95 F355, motronic 2.5? I'd like to be able to get a rebuilt unit before I go to my mechanic's shop with the car.
I suspect that I may have a reason why these alternators die so frequently, stay tuned for a fix.

Thanks in advance, Al
