After the incident (drilling F-1012D to wrong size, also messing up F-1014) I had to re-order these parts of course. They arrived just two days ago, so preparing the parts (cutting the angle, deburring, resizing holes etc.) first, then priming, and today I got to install the F-1014 (Aft Deck), and the F-1012D (Elevator Stop) mounted on top of F-1014. Finally!
