Clutch creak / firewall crack?

[MXHOWES at aol.com]

Got the same creak on my 4KQ. The firewall is solid and doesn't flex, but  
half way down on the peddle it gets real hard and starts to make a creaking  
noise and it almost feels like it is sticking when you release it. I've  lubed  
everything is sight because that is just what it feels  like but it only seamed 
to get worse. The funny thing is that the first time you  step on the clutch 
in the morning it goes smoothly to the floor, then gets  worse with every 
shift.
Any suggestions?
 
Thanks, Jim
