Is there such a thing as colored guage rings ?? You know, so that you could change the color by slipping them over/around the guage that is already mounted in the dash.
Depends on what brand gauges you have. Most of the Livorsi series (http://www.livorsi.com/catalog/gauge_styles.htm) have different color rims that just snap on. I don't know of any others that do. I changed my Smartcraft rims (made by Livorsi) from chrome to black.
