So Jeff, if I read your post correctly and the clarification by Lew, all AAR that you have seen or have pictures of have the convertible caution statement on them, correct?

When I got to that point on my car I ordered the decal and label kit from ECS and they sent me the one with no caution for my 407 built AAR. I know Dave usually researches things well beyond most so I wonder what information lead him to no caution at that time? It is possible that he didn't give it any thought but it would be strange from my experiences with him that he overlooked the 2 options and a switch over date.
