clutch sounds

[j.honor@comcast.net]

74-tr6;just completed 370 mile road trip, beutiful without incident, except for 
a growing, 'metal rubbing sound' sounds like a high pitch spring steel 
sound-hum a few bars.. when I depress the clutch pedal, seems like clutch not 
fully disengaged.if that is it, at this point no drag feel on lcutch action. is 
this the first warning signs of new clutch, throwout bearing, or adjust cluctch 
slave? all other action on engagement during up and downshifts appear strong 
without noticeable problem
