I had a problem come up with my car yesterday. I think the clutch isn't fully disengaging as I'm getting a slight grind in gears 1-4. Where does your clutch start to engage? Mine is about 1/4-1/2" off the floor. Also my clutch pedal stuck to the floor for the first time yesterday. We have another 5.0 also and the clutch starts to engage much higher off the floor, about halfway. I'll be taking my car in soon. Gonna see if I can pay the difference to have the Boss clutch put it.
