I decided to move the angle of attack to the left forward bay (front side of the middle bulkhead). I did this some time ago, but now I realize that removing and re-mounting the AOA computer box will be pretty difficult unless I install the plate nuts on the back side of the bulkhead so I can get to the screws easy once the left avionics panel is removed. The top plate nut was easy. I was able to squeeze the rivets. The bottom two I needed help. Bob Eggelston happened to come by and he helped me accomplish the task. Took forever to do it.
