If you just have to have OEM, call around to Nissan dealers in your area and find a knowledgeable parts person. I've had small items like that given to me free or extremely cheap because they had been sitting on the shelf for a long time (most ppl aren't as obsessive about such things heehee).

Hit the nearest junkyard.

Edit: Try calling local car mechanics. They may have some laying in the bottom of a toolbox, left over from a brake job.


While you're at the parts store, grab a small (toothbrush size) brass wire brush. Give the sides of the nipple (try to stay away from the end) a few swipes, put a little oil/grease/anti-rust on it, and install your new cap.
