<VV> rotating rear mount: really?

[Ronald Choy]

On examining my failed '65 mount, I see that the downward pointing 
studs are driven into their holes like wheel studs. When I started 
torquing my new mount (50-60 ft.lb.) the studs started turning at under 
45 pounds. I'm sure the new correct nuts are tight enough and won't 
unscrew themselves, letting the engine down.  Is there a great 
possibility that vibration would wear out the stud heads and drop the 
engine catastrophically?

   My theory is that since the nuts are tight on the stud shaft, they 
won't loosen. The studs, free to turn, won;'t turn much, and should 
last until the mount itself wears out.  D'ya think I'm right? I really 
don't want to replace the mount yet again.  After all, I might get 
another mount with loose studs.  Comments, anyone?   -ron 65,66
