I thought Id share what I've learned about our GX roof rails, racks, etc. All three versions of the GX have the same roof design. The premium and luxury versions have flush roof rails and overtrail has raised rails. The Toyota LC 1958 version has no roof rails. I was able to order parts from the Toyota to remove my overtrail rails and make it flush.
On the overtrail version you just remove the rails, install 6 new brackets, 12 new bolts and 6 trim caps. You use the existing rubber trim pieces as is. On the premium and luxury versions you would have to also buy the rubber pieces that go in the middle of the roof channel between the mounting brackets.
The photos below are the best I have at this time. I also included a screenshot of the parts needed to do this.
On a side note, I also installed 1" spidertrax wheel spacers which you can see in the photos below. It makes the stock overtrail wheels just about flush with the fenders.
