I am building an 87 mustang GT as a race car for my friend who owns a couple racers. The car was all stock except for a 120mph speedo when he handed over the keys. I have since ditched the original 5.0 for a 4.6 from an 05 GT. I added a supercharger and the result is that the speedo runs out of room whenever I go past 4th gear (its got a new six-speed Tremec). Anyone know where I can get new gauges, preferably matching the racer look and going up to at least 200 mph. (I'm running 18 pounds of boost for 650 horsepower and after I finished stripping it the car weighed 2103 lbs)  

What kind of gauges are you looking to put in? something factoy, or aftermarket?
