Iron rocks 2x6 supports tie in between 2x6 and the B Pilar. They kind of fill /reinforce that gap. Great idea. I bought the 3/16 wall 2x6 tube and plan on using those instead of k sup's product.
I'm in AZ. I go wheeling with AC on in 115 degree heat in my XJ. I got the aluminum triangle hood vents off Amazon. I also have the k fab hood lift spacers. The k fab overhauled injectors solved my heat soak issues. Stock radiator and fans. Just don't shut it off on the trail. Lol.
