I have a 1970 Plymouth Cuda, 340 pistol grip 4-speed. The clutch spring right above the clutch pedal (over-center spring) has been making noise like an old creaky witch. Tried putting all kinds of grease on it lithium grease, wd-40, etc still croaks like its in pain. happens every time I put the clutch in to engage an gear. Anybody know of a solution? All solutions are greatly appreciated.
