rotor warpage(?), '88 5kcstq

[auditude at neta.com]

Hi Kneale and everyone,

Actually, the vibration doesn't even change much during braking.  I 
don't feel it in the pedal.  It feels too pronounced to be flat spots.  
It's more of a harder type of a shimmy.  I think I know what it might 
be.

Right now, I'm thinking I shifted the motor and messed up the 
motor mount(s).  I will do a more thorough check later, I've parked it 
for the meantime.

When looking at the oil pan underneath, it seems like the flat 
bottom of it is not parallel with the ground.  I think it's lower on the 
passenger side.  I'm aware of the whole inter-relationship of the 
right side mount, heat shield and air hose, and consequences to 
the EM.
