Another thought to help isolate it:
You'll need a clear stretch of road with few other vehicles, if you can find one with a slight downhill grade so much the better.
Accelerate to 55 (decently into the range where the vibration occurs). Shift to neutral and let of the gas, see if that has any effect on it.
This test will mostly eliminate engine/transmission possibilities, which are remote anyway, but at least it's simple category to eliminate.
