Datsun Z Service Manuals / Part Diagrams:
Xenons30.com – the whole gambit and more
CarPartsManual.com – fuzzy part diagrams, but points to nearly every part and part number for the 280z (240z, 260z)
4Moores.com – 280z EFI manual

Retailers:
Motorsport Auto – Great selection, most of it Genuine coming from Nissan Motor Co. LTD, but really lacking on the picture descriptions.
Black Dragon Automotive – Their free catalog is great because of all the diagrams and descriptions. And it’s very handy to have a quick price reference in a physical catalog.
Rock Auto –  The kitchen sink of 3rd party / OEM parts on the cheap
