Pedal has to go to floor and still get some grinding

Did you use a kit or did you use parts from another stick shift car? I have had problems like this in the past and am still having clutch problems. I have a sneaking suspicion that my z bar is in backwards. One arm is longer than the other and the system acts like the angles aren't right. I had to cut off the adjustment rod because it was too long. I have installed 2 different clutches and could never get them adjusted properly. They always released too close to the floor. I hope I can spend some time tomorrow and flip the z bar and see what happens. Does your clutch pedal return to the top or does it stop an inch from the top? toolmanmike
