Hi, Grady. Thanks for your interest in this issue. The clacking sound was definitely related to the engine speed rather than road speed. What I mean is that the sound did not decrease based on the speed I was traveling, but based on the decrease in rpm. I could tell that because I tested by traveling the same speed in different gears, and simply taking my foot off the accelator. If I was going 35 in 3rd, for example, the clacking would be slower than if I was going 35 in 2nd.

For lifting the car I put the jack under the sump plate ala Wayne's book. I then jack it up and put jack stands under the torsion bar ends just in front of the rear wheels. I then lower the car on to the jack stands, leaving the jack in place as a safety.

Finally, the noise is/was not gear dependent. It clacked in every gear - even reverse.

I "think" the clutch is now properly adjusted, but I have one of those rather cheapo micrometers. It does feel much easier to depress than it did when the clacking was going on.

Incidentally, I'm still taking the car to the shop to make sure everything is up to snuff. My confidence in my own mechanical ability is on the low side.
