You will not need the removal tools. The radio is held in by four bolts.
To get to them, take off the trim panel by removing the 2 bolts in the picture. You'll need to lower the ash tray. There are also clips, so gently pull the trim back.
All you have to do to mount it is take the brackets off the Ford radio and bolt them to the Pioneer unit.
Definatly get the harness, it will make the wiring a snap.
