Thanks for the input guys. The wheels were the actual culprit. They were stamped steel wheels and were way unbalanced. The guy at the tire shop was amazed that I did not have more instability problems than I had. He said the American Racing wheels (Cobra style) that I bought were in perfect balance. But, the tires (Cooper Cobra GT's) were not that balanced. I bought the tires for the look and not for performance. They are good tires but a little hard for the Cobra. The guy at the shop basically said the balance was out but not way out. To get a smoother ride I would have to go to a super performance tire like on a Corvette. I am going to look into tire shaving to get better tire balance but I am not sure anyone does that in Phoenix. Regardless it rides 90 percent better than before and that is great!
For now, it's on to the next project. Mufflers, and Differential cover. I am also looking at Cobra AC pedals from FinishLine. I figure may as well stimulate the economy
