I just bought a 94 mtx sho, and i notice a strange noise whenever i drive the car over around 60 miles per hour. It sounds kind of like someone is pouring bb's all over my windshield, not very loud, but a strange sort of tinkling sound ive never heard come out of a car. Any ideas on what this is would be great. Also, the car starts shaking around 75 or 80, so im assuming i need a wheel alignment, i dont know if that has anything to do with it.
