Getting the lower cowl on my -7A was four-hands work during the cowl fitting process. Then I saw a famous airshow plane at AirVenture with the RIGHT half of the cowl removed... light bulb! After more study and a bit of glass work, this is what it looks like.
>> No fasteners in the cowl inlets.
>> Nose gear fairing is integral with cowl halves, no separate pieces.
>> Top and bottom seams are piano hinge. Firewall seams are quarter turns.
>> Top pin is accessed through a flush 'badge' behind the spinner.
>> The bottom pin is removed from the rear of the air exit duct, and is self retaining, by the spring hook formed in the handle end, see pix.
Bottom hinge is offset one inch to the right to clear the nose gear. Top hinge is offset one inch to the right to have some semblance of asymmetry.
