Thank you for those, I have tunnel flares also, I was hoping to use the hooks on the bracket that comes from the running board edge up to the tunnel for those hooks. I was also worried that the rivets may not be long enough, which was why I was looking for your mount location.Here is my setup, used the clips for the rear instead of the hooks, they don’t work with the flares and installed the stays for the front. See pictures. I used 3/16 bit and just drilled through tunnel. Where my stay is was 2 layers of tunnel so to speak, use the longer rivets.
