Clutch Trouble, Trying to diagnose a shifting problem. Options

[rebelmdot]

First and foremost, I have used the search function and did not come up with what I was looking for.

My car will not go into gear. I resurrected a car that had been sitting for 6 years. I drove it for a week and put 200 miles on it once running. On the way home on a Friday evening it started becoming very difficult to get into gear even with the clutch pedal to the floor, and ultimately would not go into gear at all. I am finally able to dedicate some time to fixing it and think after what I have read, that it is the clutch cable, the clutch tube breaking loose, or it may even need a new clutch as I do not know the condition that this one was in when it was parked and 6 years of sitting could not have been good for it. What is the best way to diagnose?

If you have a thread, a link to a thread, or suggestions on how to use the search function to get to a useful thread, I would appreciate it. I am sure that there are many on each of these, so if there is a favorite or one that would be most useful for a newbie mechanic, once again, I appreciate any input.
