90GT347

I have recently bought a 1990 gt and I have began to notice a vibration coming from somwhere in the rear at high speed. It is especially noticed when pushing the clutch in to get to 5th or in 5th gear. I have some ideas of my own on what the problem may be, but I just wanted to inguire and get someone elses opinion too.
