This is a discussion on Anyone try Stewart Warner gauges? within the Interior Mods forums, part of the Tech & Modifying & General Repairs category; http://www.42draftdesigns.com/sw.htm...
I've never heard of them. The gauges themselves look nice. From the page it sounds like you might be able to find some info from a VW board since they seemed to be aimed toward that market.
They look very similar to autometer gauges, and the connections seem exactly the same. Possibly the same manufacturer?

Possibly. I know on these you can choose from a variety of LED lighting options though. I have heard of this company (in a good way) before, but never really knew anything about them.
