With the higher cabin comes a different piece G-224....longer with a notch in it. Positionned G-224 where it goes and find the right measure to do the bend that will match the bottom of the false rib. I spent 4 hours to positionned and bent and repositionned, etc, etc.....then drilled in place and clecoed. I have now to put the little piece of alu. that come with it to mask the notch.
