Default I'v got an issue

My clutch disc split about 2k ago, so i just got a new valeo replacement clutch disc and gave the pressure plate and flywheel a good cross hatch surface. Well now thats it all together and running, it has very very good bite, and minimal hop, but has a high speed vibration at about 2000rpm, or when you get over about 95 it gets pretty bad. I dont know what it couold be to cause a vibration at a certain rpm and high speed. U joints are good, there was not a single vibration before the clutch went. When the clutch split, it did take a tiny chunk of the pressure plate with it, but i wouldent imagine it could be that.

Try flipping the driveshaft if it does it while driving in the upper mph range.

Seeems to only do it while driving. I'm almost certain its driveline and not engine. It started when i got the car back together after fixing the clutch. I'll flip the ds and see what happens.

Yeah i"ll give it a shot. Thats the only thing that would make sence at this point because it had no vibrations at all before my clutch went.
