Those gauges are Stewart Warner stage III and they are from the 70's. You could find some of them in cobra mustangs, DeTomasso's and a couple of Lambo's had these in them. I had most of the gauges from an El Camino project and decided to reuse them for the old truck. I like how the odometer is vertical !!
If you have not seen how these where mocked in please take a look at my photobucket, it takes a lot of time to make regular gauges fit those F600 holes.
