I too have difficulty getting small parts recently from a couple of different Nissan dealers, and they were for a CA18/SR20 still current stock! As a rule I have found the salespeople disinterested and borderline rude. I do have some idea of how these places operate and can somewhat sympathise with the position of a salesperson with a full plate and having to take a disproportionate amount of time for such a small item. But at the end of the day, these parts have to come from somewhere, and the impression they leave on me at the end of the day just might make a difference when I decide to buy a new car one day.
