Attaching the riblets wan't difficult, just a bit tedious. They have to be drilled through the rear channel and into the rear ribs., There are also riblet gussets and the large inboard gussett that have to all be drilled in sometimes tight toterances in order to maintain edge spacing requirements. I couldn't follow the measurements specified in the directions exactly. If I had things would have been off. I had to measure and place each component as I went along. I'll post more on the riblets when I actually attach them later.
