I have a 2004 Cobra, and would like to install a tachometer with skip-shift light somewhere on my dash. I am not sure how this can be best done without damaging the dash (I do not want to drill holes if at all possible). Is there a bracket that can be screwed somewhere inside the dash, just behind the center A/C trim piece that extends out on the side which can hold the tach? I have seeing some tachs in pics, but not the detail behind the install. Any comments, help, guidance, etc will be greatly appreciated. Thanks in advance.
