You may want to check out an instrument company called Aurora Instruments. I think their website is auroragauges.com. They have a pretty unique system of creating any gauge anyone could want, and they also have a large selection of gauges to choose from. I saw them at SEMA and checked them out.

I think what you could do is take your faces and put them in their gauges, so you'd have the original look. I know they can do anything, and for less money than other gauge companies.
