Suggestions for flathead temp gauges?

I going to install 2 mechanical temp gauges in my 37 Ford to monitor both sides of my 59AB. I've been looking around on the web but haven't found a good solution yet. I want 2 simple matching gauges with black faces. I'd like them to be vintage or look that way. Anybody have any suggestions for a good source for gauges? Thanks in advance.

 

My suggestion would be Stewart Warner. You can get them at Speedway or you can still pick up some originals at swap meets.
