I know this probably won't help, but it's worth pestering them or any Nissan dealership to try find the part you need. It has to be available. I used to work at a car dealership, and then a motorbike dealership - both as parts advisors. Literally every single part for every car/bike was available, right down to the last nut and bolt. And if it wasn't showing on the system, we would always call the factory to order it straight from them, as they will definitely have one available. Just ask them to call the factory to se if they have one there, they can't exactly say no because they want your business.
