I just got finished with the installation of the exhaust preheater body and tubing to the air cleaner on my 69. The new clamps that come with the tubing clamp is something I don't remember seeing before. I believe they are called single ear clips. The tool I've seen for this type of clamp is called "Ear Clamp Pliers" one manufacturer is Knipex. Am I on the right trail here or is there some other tool to use to tighten these clamps?
