Suddenly Grinds into Gear?

[nolv4v8]

I was driving with my friend last night in his 91 GS Turbo and something weird happened; as we entered the on ramp to the freeway he went to shift to fifth and it wouldn't go into gear, kind of like he wasnt using the clutch, but he was. He wasn't beating on it as we entered the freeway so I don't understand what could have just given like that. Now it seems that the clutch isn't disengaging so he can't shift at all. His pedal used to engage right at the top of the travel. He has no mods done to his tranny/clutch. I haven't looked at it in daylight yet, but I'd like a few suggestions before I take a look at it so I know what to look for. So far I am thinking it could be: clutch master cylinder, slave cylinder, clutch fork, or maybe the pedal assembly. If anyone has other suggestions please let me know. Thanks

the 34mm stake nut on input shaft might have popped out.
