Royce, Thanks for checking into this so thoroughly. Since the '77-'78 tanks have different parts numbers from the '75-'76, that may indicate a different mount or coating or something simple. But the fellow I'm doing this for is not in a position to modify it if it doesn't bolt right in. I'll stick with the '75-'76 model years. Thanks, Mick

Other than the 2 parts numbers, was there any indication of capacity? If capaciity is identical, I would think the tanks would be interchangeable. Does that make sense? OR... do you think the different part numbers reflects a change in mounting hardware for the '77 & '78 models?

As a new member, I hope I'm using this forum correctly. Can anyone tell me if the fuel tank on a '75 280Z 2+2 is interchangeable with the tank on a '75 2-seater? If so, does it follow that the 2-seater 280Z model tanks in '76 - '78 are also interchangeable with the '75 2+2?
