Figured out the clutch issue. Pulled the clutch cable. Naturally it's fine. The clutch arm is cracked right at the outer end of the clutch hook shaft and the clutch tube broke free at the front mount. I also found that good old Al cut a 4x6" access hole in the passenger side of the tunnel. That was bitter sweet.
I'll take the arm to get welded tomorrow. I will need to figure out what to do about the clutch tube. I can't imagine I'll find a lot of people willing to try welding that sucker back on.
At least now I know what the clicking noise was. Must be something about the way I drive. I broke the pedal on my 71 Ghia in the exact same spot thirty years ago.
