TR6 Clutch Question

["Mark S. Lepore, MD" <Sirmoog@ix.netcom.com>]

Yes, a "new" problem with my TR6, hopefully a minor one.  Starting this
weekend, and progressively worsening, it is very difficult to get the
car into gear with the clutch fully depressed.  I first noticed it for
reverse, but now it holds true for all gears.  I need to use
considerable force to engage a gear, an even then it is only with a
"clunk" and a little grind.  It is almost as if the clutch pedal can no
longer be depressed far enough. 
Any ideas?  Perhaps just some form of adjustment?
Thanks a bunch,
