To put a normal din sized stereo in you need to buy an adaptor form ford/halfords/net etc ... once you have the adaptor, (which is basically got a slot for your average sized cd player, and another slot that can be used for whatever) you have to cut the horizontal bars on the dash, where the ford CD player was, and file them off at the edges, then simply slot the adaptor in the space, and fire the cd player in as normal.
