Brief Description: Center Section: Right Corner Rib
The corner ribs were not prepunched for some reason. I had to trim the ends just a bit and then flute them in order to get them to fit perfectly to the outline of the bottom skin. I made sure they were clamped tightly in place and then used the prepunched holes in the bottom skin as a template to drill the corner ribs.
