How to determine if car has the right year parts

[Effers-Iba]

Hello fellow Datsonians. I'm new to the forum. I just picked up a 67 Datsun a few weeks ago and have been doing a lot of learning thanks to this awesome forum. I"m curious if my car has the correct style grill and seats for a 67? I see this style grill mainly on 68 and 69 models. The seats were clearly reupholstered at some point but again, not sure if they are the original seats. Did I purchase a Frankenstein car? Any info you can provide is greatly appreciated.

Grill is from a 2000 cc model, not a bad thing as it is much more valuable than the correct 1600 grill. Seat upholstery (not sure about the seats themselves) and door panels are not original, but look well done. Mirror pedestals don't look right (passenger side looks different than the driver side?) could be Datsun, but I don't believe Roadster. The two chrome plugs on the front valence covering the Fog Light mounts are not original. A few more pictures of the dash and engine would be helpful. Looks pretty clean.

Don't sweat it if something is not correct. Drive it and enjoy it
