The front cabinet has dropped approximately 1/2 inch on the passenger side as has the side cabinet on the same side towards the front.  I have managed to access the side cabinet mounting and discovered that the furring strip was split when installed and the mounting screw run through a coax cable and into the insulation; did not catch the frame.  Now trying to get into the ceiling cover of the front cabinet; passenger side and have been totally unsuccessful.  Is this cover one piece running the entire length of the cabinet?  Any ideas as to how to remove that covering to access the mounting?
