Hi-
no I specified bottom bush .
It transpires that they are available as a sperate item from MGFNTFBITZ.
Not cheap but a fraction of the cost of a new damper unit ,especially since the springs and dampers are usually ok .
The upper bushes and lower bush unit are the culprits and that makes it a worth while job to refurb an existing front or rear shock assy especially if you have the soft shockers fitted to your 2005 MGTF already and it failed MOT on bushes.
What I need to do now is work out if I can remove and refit the lower bush using home DIY methods
