Vibration over 40 mph.

Well, I got to drive the car about 100 miles this weekend, combination city, highway and a burn out! It is smooth as silk. I guess my problem was the horizontal alignment all the time. I ended up moving it 1/2" towards the passenger side at the trans mounting bolts. Thanks for all the help everyone! And thanks to @oldkimmer for calling me back. I really appreciate your advice. Now I just want to drive it!!!!!
