Clutch issues. Can't put gear in while engine running

Sebastian said
Ok so I spend the day troubleshooting and the issue is the following:
I'm not able to put the car in any gear while the engine is running. When engine is off all gears go in fine.
Now I noticed when I push the clutch I can hear and feel touching at about 3/4 way in and it goes away if I keep pushing but I'm not able to put it in any gear then. Now I just noticed that just before that 3/4 way in the clutch is actually disengaging and I can put the gears in no problem and the wheels spin.
So I tried to adjust the fork and move the two nuts from all the way to the end of the rod further up.
Now to resolve the issue I'd have to move it up quite a bit and the clutch pedal won't come up all the way anymore.
Question is am I missing a spring or something? Or is the clutch not supposed to engage again if I keep pushing it in further after it disengages?
Or what else could it be?

Thanks a lot!

hi, if you keep pushing pedal down and it won't let trans, go into gear, you have pushed fingers into the disc. how thick is your disc?? a friend of mine had same problem with his 64 dart, discovered, the disc was way too thick. the fingers are already too far down. limits travel and release. the disc was from brewers, it was .340 thick, standard disc is .305 thick. we ended up shimming the pressure plate, .050 to get everything correct. it was a mcloed pressure plate, B&B/long style. just food for thought!!!!
