Default Clutch problem

Hey everybody, my apologies if this has been asked before but I've searched 15+ thrds and haven't found my solution. I think I lost a spring in the press. plt. but not sure. I'm 58 yrs young and don't reallythat excited of spending a day laying on my back!!
Many thanks in advance!
Here goes..
Preliminary information..1970 L46, clutch, t/o brg, pressure plt, pilot bush. installed 1985. 1993 full restoration, complete trans rebuild, clutch fork, trans mount, pivot arm, all shift lever bushings, resurfaced fly wheel etc. etc. 28,000 total miles on clutch, 7,000 on resto parts. I was out driving one day and all of a sudden it seemed difficult to shift, meaning I needed more force to engage/shift. I could always shift with 1 finger. Absolutely no slipping, hooks up and goes. I drove home and went through the steps for adjustments. Disconnected the return spring. Loosened the two nuts on the adj rod. Tied the clutch pedal up to the steering wheel. Brought the bottom nut up to the slider block then screwed it forward 2.5 turns. Tightened up rear nut. 1 1/4 inches of adj. left on rod. Aprox. 1.5 in free play. As I depress clutch, 4/5 of the way down it feels like I'm overriding or over extending the press. plt spring steel fingers. Re-adjusted 2 more times...Not much better... The odd thing is, 1/4 turn of adj nut either way clutch won't disengage.. I didn't think the adjusting window is so small. Do I need a new pressure plate?? Any advice or directions is most appreciated.
Tks.

Something is likely wrong with your linkage somewhere.
I've seen the retainer clip on the clutch fork break off. Then the fork does not sit correctly on the ball stud. You may be able to gently remove the rubber dust cover on the fork and peek inside with a small mirror, without pulling everything apart.
Good luck.

Thanks for responding.. Are you talking about a clip that holds the thro. out brg to the fork?

No hes talking about the spring steel clip that holds the fork to the bell houising ball stud. Though it could be that the spring clip at the throw out bearing could be mispositioned.

If it something that just occurred all of a sudden chances are something has come apart.

Is it odd that I have only +-1/4 turn nut adjustment?? Usually if a mechanical clutch is out of adj. it takes more than a 1/2 turn to bet it back in specs????NO...

If the stud is moving on the fork it will do all kinds of strange things... Below is the spring that he's talking about.

I'd pull the boot off the fork and have a look inside. Wear on the pivot ball can do the same thing but is unlikely to give you that much change. Most other issues in the linkage from the pedal to the fork can be adjusted out, but will cause sloppiness in the movement of the pedal. (worn holes in the levers on the bell crank, worn pivot clevis etc.)

One other thing you may want to check is the ball stud on the frame. If this has become loose it would also make your car do odd things.

Thanks for the info. All of those parts are new, meaning 7,000 miles ago and 20 yrs ago. I went out to check but my youngest son's Z28 is in the way... no keys anywhere!! Can't get it out of the garage. I will check all mentioned points.
Thanks,
