Thanks for confirming. I have the flares that I had on my old '07 4.8 (Sapphire Black like yours). I'm going to install them in a couple of weeks when I am sure we finished with snow in the Northeast.

I would agree that 8 should be more than enough to keep them in place. I am going to out a rubber block in them to keep water out.
