So here is the p/n, thanks to CT: 41014-7S010
It looks to be about $23 per side. But the original question stands, does anyone know if there is any reason to change this stupid thing?

EDIT: I got this response from NissanParts in reference to the p/n being before or after the final brake fix TSB:
the part number (above) is the replacement part before the TSB, the new part is a kit with a pair 41014-ZC025 KIT
