Rockauto lists (2) for my 1999, a 70-amp and a 85-amp. When I replaced mine about 6 mos. ago, I just purchased one from eBay. I wonder which one I got? As for the Maxima alternators, I also looked on Rockauto and it appears the 1999-2000 ones are similar except that one mounting ear is placed at about 10:30 o'clock instead of 12 o'clock. Wonder if it would mount up OK.
