Here's the situation. Th previous owner of my '48 half ton cut the tube from the heat gauge to the engine. I acquired a second gauge cluster with a complete heat gauge, but when I went to swap them I noticed that the replacement gauge has a longer needle and it's painted white, while the original is red. I dont see a way to change the needle, and it looks like the tube is soldered in. Is there a way to remove the tube from the one gauge and install it on the other? :confused:
