Does the flywheel have locating pins for the pressure plate? Perhaps one of them (or all of them) aren't in place and the flywheel has shifted a bit, causing the vibration at higher RPMs.
This would show up more when driving since the pressure plate would have more pressure causing a pronounced out of balance feel. Just my 2 cent's worth.
