I'm hoping you can help me identify a problem with my 2002 Corvette Z06. I bought a transmission and differential from you via South Georgia Corvettes in Thomasville, GA, back in 2012. The car was a mess when I got it back, and it took me over a year to get it mostly straightened out. During that time I had to replace the torque tube with driveshaft because the carbon fiber driveshaft that Pfadt sent for my car was incorrect and too long for my vehicle. The installer did not catch the mistake, nor did South Georgia Corvette when they worked on it. So the torque tube got destroyed, as well as the clutch, slave cylinder and flywheel. The pilot bearing had been bored into, but there didn't look like there was any damage to the crank itself.
Anyway, I've had an intermittent drive train noise ever since, and possibly even before all the above was replaced, but I just can't recall with all the other noises the above damaged caused. The noise seems to happen most often going from a dead stop and when I am taking pressure off of the clutch pedal so that the clutch pressure plate engages the disk. It will sometimes, although more rarely and less noticeably, happen when changing gears while accelerating. Again, this is when I let off of the clutch pedal and the drivetrain picks up the load from the clutch engaging the disk. Happens in reverse as well as forward gears. I can often feel a strong vibration associated with the noise directly on the shifter handle.
I've spent a lot of time looking at videos on YouTube and asking around, but so far just cannot pin down the most likely cause of this noise problem. I've been trying to wait it out to see if it will just work it's way out, or be consistent enough that I can make it happen on demand 100 percent of the time, but so far that's just not happening.
But obviously it puts me in a bind, as I just do not trust the car to not fail me on a long trip with it and it's wearing on me.
I am prepared to pull out the drivetrain myself and fix or replace whatever needs to be done, but I would REALLY like to have an excellent idea of exactly what I am looking for. So I'm hoping you can give me some guidance. I am putting a link here to a YouTube video I took back in 2012 to show you (and let you hear) the noise I am talking about:

Again, this happens when I am taking pressure off of the clutch pedal and the clutch is easing into moving the car forward. At all other times there is absolutely no noise from the drivetrain that I can determine. I figure you guys have probably seen more than your share of drivetrain problems, and hopefully heard this exact same thing and KNOW what the problem is.
So would you mind helping me with this? This has been dragging on for a long time now and I would really like to feel that my car is finally finished and the problems GONE.
Thank you for any help you can give me with this. If there is anything I can check for you, I have the car up on my lift right now and can take videos with audio, or anything else you would need.
