94 mustang gt has a vibration that gets worse the faster you go. At 80+ it gets so bad in the gear shift thatyoucan't hold it and when you push the clutch it gets worse at that high speed.
Also my driveshaft has been rubbing in the middle. It's very shiny, maybe even worn down some
Could be a mutiltude of issues since its been going on for a while. Bad universal joint, damaged ( out of balance ) drive shaft, possible bad clutch, throw out bearing and or fly wheel.
