I had this door for several years and it's a new factory never installed door. I belive its for a 2+2 but I am unsure if its for a 280zx or 300zx any help would be appreciated. thanks. The first photo with the meausring tape measures 51"

Must be a 300, the 280zx did not have a wing to mount the mirror on.

51" would be a 2+2 S30 2+2 door was about the same size.

yup, z31, you can tell by the bodyline through the door, the doorhandle, and the "wing" as Will said!
