Hi everyone. I was browsing the internet this morning and came across a really nice '62 Impala SS. They showed some pics which I could enlarge, and I saw something interesting. This car had a temperature gauge with a sweeping needle between C and H. I've never seen this before. My '62 and all the others I have seen always had a green and red light. This gauge looked like it belonged there. Would this have been optional or maybe it doesn't belong there?? Just curious. Thanks, Carmine.
