I saw a message a few week ago on a similar problem but could not find the post. Looks like I have a similar problem.
New Rebuilt Wide Ratio Toploader
Centerforce Dual Friction Clutch/PP/Throwout bearing/Roller pilot bearing
Modified Z bar linkage to clear my headers
11" refinished flywheel
New motor mounts
Vehicle has less then 50 miles on it. I was driving the vehicle in stop and go traffic. I had adjusted the clutchrod the night before and it was shifting great the next morning. After about an half hour my clutch pedal began to squeak another 1/2 hour and the vehicle would shake violently when you would engage the clutch in 1st gear. I could start up in 2nd gear with no shudder but first gear was Very Bad. Vehicle was hot but it did not geta any better after I drove it around and cooled it off.
I thought it had just came out of adjustment but everything was nice and tight.
I did notice what the squeaking sound was. My upper clutch rod (Pedal to top of Z-Bar) was rubbing the edge of the firewall hole. Something had shifted inboard but besides rubbing it did not seem to effect the clutch actuation.
Tonight I will check for a broken Motor or trans mount (doubt it). Anyone have any suggestions on what is the cause of this issue. I will repost tonight after I take it for a spin and see what it does witha cold engine.

Maybe some thing came loose inside like the flywheel or pressure plate. Broken pressure plate. good luck

Brand new Centerforce Dual friction Clutch and matching presureplate. Hope that is not the issue. I am really hoping its a linkage adjustment issue. It was working grat for a little while. I dout I cold have damages/hotspotted anything in an hours drive time. I have been pretty much babying for the 50 miles of break in it has gotten.

Did you have enough play in the pedal so that the clutch would be fully disengaged? I am just grabbing at some ideas.

I am at the opposite end of that.. Because of the mods I made to clear the headers I lost a bit of pedal ratio. I am within 2" of the floor when the clutch disengages. But it does fully disengage.

Keep me posted on what you find out. I am out of ideas and I am sure you are going through the norm checks like u-joints and mounts and so on. I can't remember what the other persons fix was to the same problem. I think it was some thing simple.
