Noel, there are 4 clips down both sides of the coach which are part of the seating.These sit into 4 gaps below the windows which lock the seats to the body.They are located on each end and the centre, you also have a clip on both ends of the chassis that lock into the seating and that holds everything in place.If you turn the coach upside down and part the body from the chassis slightly you'll see where they are located.I used a small flat head screwdriver to do this, just take your time so no damage comes to the model.
