I went blanket, I have seen pictures of failed carbon fiber shield. Fits fine on my sb 727. Linkages need figuring out. If you run kick down its a bit more difficult. I took a piece of square tubing and heated it. Made a window through the blanket for shift linkage. You could just make a brace to keep the blanket off the linkage. I started down that road, but it puts the blanket that much closer to the exhaust.
