Instrument Panel, hinged, Rear Cockpit
Hinge Pins included.
When an instrument is surrounded by three cross head screws and one slot head screw, this is a clue that only the slot head screw needs to be released to remove that instrument. Notice the rear encapsulating bracket in the picture.
The slot head screw releases circumferential friction via a wedge mechanism, and the instrument, once its rear facing connections are undone, will pull forward and out.
