[DeTomaso] a different clutch question

[STEVE COX]

My clutch is extremely stiff.  Since this is my first
Pantera, I don't exactly know what is correct, but
even my friends that get in the car remark about how
stiff the clutch is.  The car is a 1971 and I think
everything is original.  I'm afraid I am going to have
to cut back on my driving time and go to the YMCA to
build up my leg muscles to allow me to depress the
clutch.  Does anyone have any ideas?  The clutch
operation seems smooth, just stiff.
Thanks,
Steve
