What's a PP? It just doesn't feel right. I have a 72 charger rallye w/ 440 and the pedal retuns all the way, and goes to the floor. I don't have to push it all the way to the floor to engage the clutch, but I am able too just the same. My RT pedal stops traveling about 3/4s of the way down if I adjust it so it returns all the way back. Or I can adjust it so it hits the floor, or almost hits the floor, but won't return back to the top without help from my foot. Must be mismatch parts or something with the clutch fingers or throw-out bearing. Is the fork shaft and z-bar unique to 440s? Car has matching 4-speed. Maybe it has the wrong bell housing with the pivot point for the fork shaft closer to the T_O bearing
