Instead of getting some heavier plate aluminum, I remembered that Chapter 690 has a sheet metal brake, so made a drawing of the mounting bracket, cut it out, and took the pieces to the Chapter hangar and bent them up using the brake. Worked like a charm, the plate was quite rigid and the adjustment screws worked well.
I did both at the same time, so when I start on the other (right) wing, the process will go quicker.
The plates that will hold the lights and in turn be mounted to the fixed brackets.
One of the light mounts fitted against the support bracket, with the edges turned up for stiffness.
Light mounted in place. The top screw adjusts up and down, the lower 2 do left and right.
