Thank you very much for your comments. Yes, I want to keep the ornament that is on hood, it is already repaired to be back on the hood. I read somewhere that this datsun was the first to enter Mexico around 1959 - 1960. I had compared the my datsun's grill with other models, so I guess it is a 1959 or 1958, at least with the information found through internet (I can add some picture), I really guess it is a 1959. I am adding a picture showing the plate screwed on the door's post, it is shown that it is a 1960.
