I did this in my stang I took out the factory cd player which is below the factory radio, and I took a piece of plexiglass, and had someone cut out the word saleen then I hid a small neon tube in behind it and when I turn my lights on the neon comes on and lights up. I also seen in a mustang catalog, not sure which one right off, they had a kit where you can insert three different gauages there. Just a ideal or two~
Bye,
Karen
