Bad clutch vibration help plz!

Ok so i put in a tr-3650 off a bullit mustang into my gt yesterday i got my flywheel resurfaced and torqued my flywheel to specs! It said to torque to 85lbs (flywheel to crank) and pressure plate to flywheel to 35lbs. I have a spec stage 1 clutch. Thing is i didnt replace both bearings! Yeah i know how dumb of me right but yeah i kept the same pilot bearing and throwout bearing! Now i have a bad vibration when it goes passed x1000 rpm. Anyone have any ideas of what it can be? Can it be because i didnt replace both bearings? Or something left loose? Im sure i torqued them to specs thanks in advance for the help guys

It could be a number of things honestly. Could even be a faulty pressure plate. It being spec I wouldn't be surprised if it was. Reason I say that is I had a bad experience with my spec stage 2. After talking to my tuner that had about a dozen laying around his shop he told me his opinion and experiences with them. He had nothing good to say at all. I know everyone has their opinions and we are all entitled to them. However the best thing for you to do is pull the tranny back out and inspect everything. Since this is a new tranny did you happen to drive or ride in the car it was in? Is this vibration just with rpm's or only while driving? We need a little more info.

Could be the throwout bearing, mine vibrated when it went out. Could pe a pilot bearing too, or you didn't center out the clutch right with alignment tool. Best thing to do is to go under there and check it out. Replace your bearings this time, I know Luk throwout bearings suck, so Id go with some Ford Racing ones. Theyre real good.
