Angry Speedometer Accurancy

Ok, I got a ticket the other day for doing 78 MPH in a 60 MPH zone. Because my speedo tends to bounce between 60-66 MPH I rely more on my tach reading. I believe between 2000-2100 RPM puts me in that 60-63MPH range in 5th gear. I never got above 2100 RPM's and now I have to wonder if I have grossly miscalculated the gearing for the car. The WSP sure in the hell wasn't buying it and right now I am afraid to go over 1500 RPM with the way my speedometer and tach are behaving. Is there a way to calibrate the speedo or tach without having to send them off somewhere to be bench tested and re-instaled later or do I have to resort to having one of Washington's States finest check for me? I plan on going to court on this one because I honestly did not believe I was going that fast. In addition, I want to make sure I understand the technical factors which could have caused or contribute to this gross mismatch and make durn sure I get it fixed promptly. Any jail house lawyers out there?
