Loud vibration/rumble just off idle. SOLVED!

[GrumpyYoungGit]

Hi all, as title says I've got a rumble,
All mounts changed (bottom and hydramount+tie rod were all shot)
New clutch and dmf (clutch was slipping and flywheel actually needed doing)
Played with heat shields pulling my hair out, it's a horrible noise and is easily audible to passers by when pulling away and even at certain revs/speed.

What's left to do?

EDIT
Had a listen with a screwdriver and found that the lower pivot bolt on the alternator has worked loose, nipped it up and the horrendous noise is finally gone and I can appreciate just how smooth this car is actually supposed to be!!
