Vauxhall cavalier 1.7D 1993 :heater matrix removal?

have removed housing around handbrake and gear lever also removed radio housing but can't seem to separate the middle housing from the top housing containing the central air ducts + hazard warning switch. The problem is on the right hand side( as viewed from inside the car) since the LHS is free to pivot ...I've looked for concealed screws/clips but can't see any...any ideas would be much appreciated.
