So those factory brackets don't go on the OUTSIDE of the roof, but you put them on the inside for strength? Where'd you get your hardware and is it stainless?
The brackets or mounts go on the inside under the liner for strength and for something for the roof rack to screw into.
went to lowes and got the hardware, they are stainless
if you order the rack fro powerfuluk they will give rivnuts to install it with...they seemed weak and the only thing it was attaching to was the sheet metal roof...so if you want it to stay put and be strong buy these mounts. and use bolts.
You can find the brackets here...

they are factory parts and are the mounts Nissan uses to mount the rack on the LE's or the nismo's.
Here's the part numbers too..

[73822N] REINFORCE-ROOF RACK,FRONT RH
[73824] REINFORCE-ROOF RACK,REAR RH
[73825] REINFORCE-ROOF RACK,REAR LH
also wanted to say that those mounts fit perfectly with powerfuluk's rack. if you decide to use these and bolts let me know and i can find the exact bolt size you will need.
