Model and year of these door panels?

[saridout]

What model and year car do these door panels go on? The owner is advertising them as being for a 75 260z, and says the distance between the lock pull and the back edge of the door is 8.5 inches. I thought that the 8.5" door panels went on the 77 and 78 models.
