WOW you guys are harsh man. You can go down to a speed shop. There usually a lot of them in bigger towns. and get a small one that has a mounting bracket. Like tey use on the local racecar track on the modified class cars. they are completely calibrate-able (for lack of a better word).

I have no faith in human perfectability. I think that human exertion will have no appreciable effect upon humanity. Man is now only more active - not more happy - nor more wise, than he was 6000 years ago. Edgar Allan Poe
