Blake, you didn't mention what year your Pantera is. Note that from mid-'72-up, there was an 'effort-reduction' kit installed in the clutch pedal linkage under the dash. This adds several links and pivot pins that run steel-to-steel, none of which have ever been greased since the car left Modena (and maybe not even then). This is, as you say- likely not a quicky spray-it-and-forget-it thing....
Note also that the mousetrap-spring on the clutch shaft regularly breaks and is not worth replacing; a new one will only break soon after you fix it, and it requires dashboard removal to R & R it.
