making HVAC, headlight, and speedo gauges
 

I've seen a lot of things about how people are making these gauges. I have a '97 Camaro RS (120 mph speedo) and I was wanting to make some gauges for it. If someone could give me some step by step instructions and maybe the template pics, that would be awesome. Thanks for the time.
