Most european ford cars provide a "runner" at the top or bottom of the radio slot, What you need is the plastic "V" clip that fits to the back of your radio. this allows you to do fit an aftermarker radio in the hole! You can buy these from any ford main dealer. Note theire are three types one for the standard "large" radio and two available with a hole that goes on the back of your radio, one long and one short. sometimes the runner breakes off if you are unlucky!
