ACCORDING TO THIS STORE---THIS IS FOR AN '86

THIS ONE IS FOR AN '87

http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_alternator--70-amps-worldwide_5842395-p?searchTerm=alternator

THE PART NUMBERS AS WELL AS THE PRICE IS DIFFERENT.....THEY LOOK SIMILAR....THE PART NUMBER DIGITS SEEM TO BE CLOSE

KEEP IN MIND, I DID NOT KNOW WHAT ENGINE YOU HAVE, I INSTALLED THE REGULAR OLE 3.0, NOT THE TURBO IN MY SEARCH

I REALLY DON'T KNOW IF YOU WERE COMPARING THE ALTERNATORS OF TWO 300ZXs ......OR OF ANOTHER MODEL

NOW THAT YOU SEE HOW I COMPARED THEM....IF MY SEARCHES WERE WRONG....YOU WILL KNOW HOW TO DO THIS

READ THE SPECS---LOOK AT THE DIFFERENT VIEWS---THIS MAY SHOW YOU THE DIFFERENCES---COULD BE THE PLUG OR NUMBER OF PINS?

HOPE THIS HELPED A LITTLE
