You can most likley either call a ford dealer and ask how much a tool would cost (specially to remove the stereo) or what i did was take a hanger and cut it in half so i can get two halfs, then stick the ends of the two halfs (should look like a V) and stick them in the holes, push each one outward and pull towards you. It may take a little bit but i got it to work!
