I was wondering if someone here would know what is wrong with the
clutch, or if any adjustments are needed. The problem I have is that
the clutch only comes up almost half way back from the floor. It
doesn't come all the way up, unless you put your foot behind the
pedal, and pull it back up.

The real problem is, it doesn't start to catch until about halfway to
3/4 of the way down, making it impossible to shift gears or put it
into a gear without it grinding.

I'm new to clutches so hopefully someone can help.

To much free play could mean the clutch linkage needs adjusted and/or
the return spring may be missing.
Could be the linkage is binding/rubbing on something. I've seen the
cab mounts rusted, causing the cab to drop and making the floor rub
against the the pedal rod that goes through the floor.
Could be the wrong length throw out bearing. Old Chebbies/GM's had
three different length throw out bearings that could be used.
Could be the flywheel has been turned to many times and and is now to
thin, throwing everything off.

if the return spring is missing, would this cause the clutch to only
start to engage (the friction point) after the pedal is 3/4 of the way
down?

how do you go about adjusting the free play in the clutch linkage?

No. It will cause the pedal to "not come up all the way"once the
clutch is adjusted properly.

There will be a rod with threads and a locking nut on it, down at the
bell housing and trans, on the drivers side. One end will be at the
throw out bearing fork, (part sticking out of the bell housing), and
the other end will go to the cross over bar. Make the rod longer for
less "clutch pedal free play". (free play=easy pedal movement before
the pedal gets hard to push) You want about a 1/2" off free play.
