What's the OEM amp spec for a 1999 Nissan Frontier alternator? Napa has a 70 amp for $140 and a 80 amp for $200. If the stock spec is 70 amps then I'm going for that one.

I cant help with any info but that the 4cyl and 6cyl alternators are different. What do you have?

Both the 4 & 6 cylinder engines had a 70 amp alternator.
