Have no idea what this issue could be.

When slipping/starting out in first I get massive squeals. This use to only happen in 2-3-4 shifts at high rpms.it has gotten worse to the stage it happens everytime starting off in 1st and also on moderate avg rpm shifts.
Once in gear it drives fine and normal.

Clutch/Flywheel info in Sig.

Sounds like your throw out bearing is going bad.

I'm not sure on the exact mechanicals in a clutch system and what each one specifically does.

BUT,
If it was the throwout bearing. Wouldn't it make the same noise as if I'm sitting there in Neutral pushing the depressing and pressing the pedal??

It only does it in between gears or engaging a driven gear.

Good point! See what happens if you increase the RPM's to around 3K in neutral and depress the clutch. Will that duplicate the noise? The noise sounds to me like a metallic screech. Another possibility is that one of the rivets in your clutch plate is loose and is screeching on the flywheel or pressure plate while the clutch is slipping. Once fully engaged the noise would stop. Southbend had a problem with a batch of their rivets about two years ago and there were numerous reports of clutch plate failure as a result. Possibly you have the beginnings of this issue.

Tried it and no screech while depressing clutch in N holding revs at 3k.

If the clutch plate is faulty (as a result of the rivets) can that screw up the flywheel?
In that thread that guy's flywheel looks fine (in his opinion).

I guess it would depend upon whether the rivet was grinding on the flywheel side or the pressure plate side. Although I doubt the rivet would cause enough damage to the flywheel to warrant replacement. Rivets by nature have to be a fairly soft metal so they can be deformed (clinched) in place.
