Speedo Wrong

[J.Larr]

I bought this 1982 280 turbo zx with a 5 speed transmission around Chistmas. The speedometer says I'm going around 62mph when I'm really going over 80mph. I called a highly recommended local speedometer and tach shop. They told me that they could only test the speedometer but there is no way that they could repair it's inaccuracies with the simple change of a speedo gear such as you would an older american car. Is this true? And if so how do you set your speedometer to read the correct speed on '82 zx. I can be e-mailed at [email protected] with any answers or suggestion that will resolve this problem. Thank You..
