Clutch Problem?
Hey all,
was driving my '74 (close ratio Muncie) around last night and all was good until I returned to pull into my garage. I was slowly moving in 1st gear and all of the sudden got this shaking, loud vibration problem. Pushed the clutch in and it stopped. Put it back in gear and it returned. Sounded and felt like it was coming from directly under the center dash area so figure it's transmission/clutch related. Clutch pedal resistance felt the same as always. The car still moved fine even with the crazy noise so I parked it for the night and decided to give it a closer test today.
Started it up this morning and went into reverse with no problem, as I was backing out it returned. Put the clutch in and it stopped...but here's a weird thing...in neutral, pushed the clutch about 95% down and the problem stopped. Pushed it all the way to the floor and it returned even though I wasn't in gear. Tested and it occurred in all 4 gears and reverse. Shut the car off, and restarted it then drove up and down the driveway for at least 5 minutes trying to recreate the problem but it wouldn't return and drove like everything was perfectly fine...how crazy is that?
Does this mean my clutch is going out? Something else? Ideas?
Thanks!
Here's the vid I took last night...

I listened to your video. It sounds like "money" to me. 
Time to pull the tranny out. Clutch is probably toast.
When you put it in gear, the clutch disk stops rotating along with everything inside the gearbox so the pressure plate is spinning along with the flywheel. if the transmission isnt spinning, it should not be making any noise.
Regardless, you gotta drop the tranny and clutch out.

You might get lucky and the bolts just came loose on yhe pressure plate, bell housing or tranny.
I would check that everything is tight first Before removing anything
