My 81 Westie clutch decided to hang-up yesterday.Heard a big "thunk," which
sounded like the engine moving on loose mounts; the clutch will no longer
fully disengage.
I think there is sufficient travel in the arm of the clutch - when pedal is
depressed, the external clutch lever will move to a horizontal orientation.
No leaks noticeable in any hydraulics, nor is resevoir low at all. Pumping

gear, but wouldnt move out of 1st gear easily, so I didn't push it. 
Shifter goes into all gears, per usual, when engine is turned off. So I
don't think I have a problem there. Clutch clearly drags when in gear and
attempting to push clutch in while Van was "coasting" down hill with engine
off (only a few yards).
So what might I have on my hands? Do I need to remove the transmission and
