Alternator Part number

So I can sound ignorant here and not at the part store, what would the part number for a 3 wire 10si alternator be at napa or other popular part dealer? Can I walk in and they would be able to help or do they have to have a year and car model to get that figured out?

Guess I should have clicked on napa first, they have a complete ag section.

NAE67178

just some info about this number this unit is rated about 60amps if you will be needing more power ask for number 7127 this updated unit of same build but rated just above 100 amps. the 60 amp was called a delco 10si the 105 amp was called a delco 12si exact same physical size and make up different electrical windings to get more power

Finally realized my tractor came with the 10dn Delco externally regulated. Found out my issue was due to a bad connection on an inline fuse all along.
