Hi there, i just got a lot of 240z 260z 280z 280zx 280zxt and 300zxt parts and a few cars to restore. I am new to Datsun and would like to know if there is a database or schematics of manufacturer's part numbers available on the internet or in paper form. Lots of parts but no clue what they are, at least most electronic parts have numbers, but which car do they belong to ? Having a reference list would help me a whole lot. Thanks in advance "G"
