A833 Vibration Issue
I have the stock bell housing. I drove the car several more times coasting from 70 mph down. In neutral. motor idling, motor off. clutch in, in neutral and in gear. As long as the trans was disengaged, the vibration went away. The vibration is there at 2000 rpm and up even with car sitting still.
We had the trans completely apart. The only things needed, were the tail shaft bushing, gaskets and seals.
The vibration is weird, it pulses, even sitting still! More rpm, the worse it is.

I'm confused. You are basically saying that
with the car stopped
the trans in neutral or the clutch pressed in........
the vibration is still there "from the engine" depending on RPM?
If so, this pretty much eliminates the transmission. There is some chance it could be clutch related
IF this is so, what I'd be tempted to do:
CONFIRM this is so with car stopped
With the engine cold, CONFIRM the vibration, then pull the belts and recheck with no belts
If no change, pull the clutch linkage, and pull the gearbox. Get the fork and T/O out of the way
If it still vibrates, pull out the clutch assy.
Obviously if it STILL vibrates, it's somewhere in the engine
THAT could be some things
Some sort of miss or low cylinder, etc
wrong balancer
wrong or modified flywheel.
Something 'lyin' about the rotating mass of the engine.......seriously different pistons or rods, etc.
Or something actually wrong....bad bearing, etc
Consider a CRITICAL cylinder balance, cylinder leakdown, vacuum gauge diagnostics, and even suspect ignition problems, bad plug wire, etc.
