Got my New 55 mechanical Temp guage tonight from Danchuck. It is for the Chevy Car. Talked to their tech and decided to see if I could adapt it to the truck cluster. I have Pictures https://picasaweb.google.com/Haylee...echanical?authkey=Gv1sRgCMDZtqPQnvyfFg#. Note the side profiles as compared to a 56 electric. Needed the mechanical as I have an older head with 3/8" npt. The face is bigger and mounting is different. It's too expensive to just cut up, so it will probably go back. Thought the pictures might be interesting to someone.
