OEM Alternator Part Number Needed

Does anyone know what the OEM or MOPAR part number would be for a 90 or 95 amp square back 3 wire (externally regulated) alternator? I've heard these called "Police Car" alternators. They may have been used in other applications as well.

I bought a brand new (not refurbished) 60 amp square back 3 wire alternator from Rare Electrical in NC last week. Since then I've been reading a lot about my electrical issues (battery continually going dead) and have decided that a stock 60 amp alternator isn't going to get the job done. I need a higher amp alternator to handle my cooling fans, etc. This company doesn't like returns so they want to charge a 20% restocking fee. They will wave this fee if I give them the OEM or MOPAR part number for the alternator I want to buy.

Thanks in advance!
