Rhys, I was getting the banging on fast gear changes (coming off the clutch quick), could not really feel play in either of the mounts (like you a few mills on the top one), but tightening the bottom mount to the chassis/subframe by no more than half a turn on the nut seems to have cured it. You may have sorted by now, if not you can get to this quiet easy by sticking your head under the front of the the near side wheel to reach the nut under the lower mount, youll need a socket on an extension bar. I also cured the play in the gear linkage whilst under there, take a look whilst your hands are dirty!.
