I actually got in touch with a member here that "runs the ship" at a Nissan parts counter. His user name is "Alkorahil" He hooked me up with new rack mounts and the other stuff. Chances are, he'll get you Nissan parts cheaper than going to your local Nippo dealership.
I'm soo trying to be a redneck. I used a small pipe wrench but, I'm sure someone will chime in with the correct tool to use.
Again, check with Alkorahil here ..
