The wing flap Drive Bracket needs to have a slight bend in it. Image 1 shows the left Drive Bracket clamped in a bench vice with the bend line just visible above the scrap aluminum angle. The aluminum angle is so that the steel jaws of the vice don't mar the surface of the Drive Bracket. To keep the exposed part of the bracket straight I clamped the bracket between two pieces of scrap 1x4 as shown in Image 2. In Image 3 you can see me applying a little muscle to the clamped aluminum bracket to create the desired bend.
