Alternator date..?

[rick3000]

There is no definitive way to get a date from that information (as far as I know). But according to the parts guide, the -01 version was installed through 1999. Since that part number has been superseded, it likely would not have been installed new after 1999/2000, or else it would be -02. My guess would be that -01 would be earlier than '99, because the parts guide jumps from -01 to -03. A dealer may be able to give you more information about when a version was superseded (such as -01 to -02), but that doesn't really tell you when it was installed. It could have come from the factory, or it could have been installed used, since it is a relatively expensive part.
