New Throw Out Fork Did The Trick
 

Just to update those of you who have been keeping track of my ongoing clutch woes; here's an update:

I replaced the TO fork and reinstalled the clutch yesterday. I made sure to grease the guide tube well also. I got the powertrain back in the car. Just to make sure, before hooking up the oil lines and CV joints, I reattached the clutch cable and adjusted the clutch so there was one inch of play. The pedal felt great, just as it was supposed to, initial load, then a break over as the PP compressed. I got everything hooked up and went for a spin. The clutch was smooth and engaged without a shudder. This whole time its been the TO fork that MM was supposed to have replaced. I'm glad things are finally working right.

The morale: if you want it done right, do it yourself.

Or: If you want it done right, don't take it to MM. ;)

Good work, Troy!
I replaced the guide tube and TO fork as part of the recent engine work, and still am amazed at how smooth the clutch is operating.
