I have an original 1968 fastback with a 289. The interior is all-original, black, however the water temp gauge does not work, and there is no tach. Does someone sell these original gauges or original looking gauges in a group or separately? I saw some of the small tachs that look like the originals, but I want to get a larger one. If someone can point me in the right direction, that would be great, thanks.
