I need to adjust it a bit but I have it installed now. I pushed it forward to get it away from the shark-fin antenna, but now I think it's too far forward. I also think it looks better with a black factory rack instead of my silver one.
It was also a bit difficult to keep it level with the curved bars of the stock roof rack. I put it on at night but I could tell today that it was a little off center. Other than that very easy to install.
