RE: drive shaft question
There is a problem with the design of mark VIII's. They shake badly at high speeds. Even my 93 did. When you put in a higher gear ratio the speed that your car will start vibrating is lowered. I think 4.30's will bring it down to about 75 or 80 mph. when the car starts shaking. Maybe lower. Granted, the one piece design is better, and a few people have gotten away without changing it. I would take a guess that approx. 80% of 93 owners have had to do it too.
If quizzes are quizzical, what are tests?
