i recently replaced my stock clutch with a centerforce dual friction. i also added an adjustable cable, quadrant, firewall adjuster, and a heavy duty clutch fork. it all worked well after the install but after my 500 mile break in and a healthy beating the clutch and clutch fork seem to be shaking and vibrating and also makes a high pitched chattering noise. i noticed that while the car is running i can push and pull the clutch fork up and down about an inch (not front and back like the cable pulls it). also around 3000-4000 rpms i hear a grinding noise in the dash.... none of this happened until i started beating on it again... any ideas what could be wrong?
