Brent,
I think I feel the vibration with the driveshaft disconnected from the gearbox,
but I don't hear the noise anymore. Trevor suggested that the driveshaft may be
amplifying the vibration.
The universals and driveshaft are rusty and I am assuming original (I haven't
had
the car long). The mounts are probably original too; I have never pulled the
engine.
There was a loud noise at 38mph when driving and before I disconnected the
driveshaft. I can't hear the noise with it disconnected. Would you mind if I
sent you a wav file of the sound (off the list of course)?
Is it possible to examine a Spridget driveshaft in place? I'm guessing the
engine/gearbox must come out to remove it?
