The noise that you heard was the tob on the clutch fingers.
The new self adjusting clutches in a current production car are designed for constant contact but the Pantera isn't.
I have seen the fingers on a diaphram clutch worn through from the tob in just 8,000 miles.
The long clutches are more forgiving in this respect. Do you know what is in there?
