today I went to push my clutch in and all I heard was a snap followed by the clutch pedal goin to the floor. At first I thought it was the cable until I looked under the dash by the pedal and saw a white piece of plastic. It's sorta like a rod and theres a small collar that slides on it and clicks. When I push the collar up against the pedal arm it holds the pedal in normal position but the slightest amount of pressure causes it to slide back down and the pedal drops. Is this piece my problem and if so what's it called? If it's something I can get aftermarket can I get any good suggestions?
