New clutch.

The clutch disk was much below the replacement limit. It was worn down to the rivets which than scored up the flywheel. Unfortunately the glazed and badly worn flywheel could not be resurfaced, so I had to a good used one. The new one is from an olde model, a 1984, therefore some pickups for a magnetic sensor are mission, but that's not a concern. That particular sensor is normally capped off in the engine bay, and only served some factory diagnostic function.

The vibrations I was getting during initial engagement into 1st gear, are now obviously due to the warped and badly glazed flywheel.

The new disk is about 8mm thick, while the old was 5mm. The original disk would have been rubber centered, so the clutch I am putting in now is at least the 3rd. Based on the mileage of the car, I doubt it would more than that. 
The starter ring gear bolts on to the pressure plate. I re-indexed it, so the engagement on the compression stroke wears a different set of teeth.
Using a couple of sockets inside each other (3/8" inside a 17mm), I aligned the clutch and installed the pressure plate.
A bit of red paint will show if any of the bolts have loosened.
  The clutch cover was pretty dirty, so a quick bead blast revealed some fresh aluminum.
Starter wires routed with new Adel clamps, and slave cylinder refitted.
