Can any explain how to adjust a rear bumper. It is perfect on horizontal allignment but needs to move back slightly as it sits to far forward at the rear wheel arch.

if your car is "Pre '00 my" then you simply loosen the bumper iron mounting bolts, situated on the underside of the rear chassis rails, then slide back.
if this does not happen, then it will appear that the actual bumper metal backing beam is crushed and will need removal to either be straightened or replaced.
If the vehicle is post '01my, then the mounting bolts for the backing beam are accessed through grommet holes in the boot floor inside the boot.

hope this helps.
