does anyone know of a company or vendor here that makes pods for mounting on the dash, above the radio area?

BD Power does X-Monitor Digital Gauges (http://www.usdieselparts.com/category.cfm?Category=770)

Stacks...check this out at stylin concepts. It's a dash overlay but it adds 3 gauges over the stereo.
