Finished the rear of the cabin.Eagle provides the option to cut out the back of the cabin, which makes installation and reinstallation of the cabin shell much easier. I opted to leave the back of the cabin in place and install a piano hinge to connect the 2 halves and install nut plates at the lower area near the aux tank. I marked the position where to 2 shell haves meet, removed the shells and installed the piano hinge section and flush riveted the 2 piano hinge section in place. Reinstalled the cabin shell on the frame and everything fit perfectly.
