I just put in a King Cobra clutch kit but I am having a little trouble. When I shift from third to fourth it grinds with the clutch all the way to the floor. It engages pretty close to the floor on the pedal so is there a way to adjust that maybe thats the problem? I only put 2 1/2 bottles of gear oil in my tranny but I heard that its supposed to take 2 1/2 or 3 Which is it?
