If you open your hatch and look on the outside edges of the top (where the wing would mount) there's only about a half-inch of material to work with. One needs to cut into the structure of the hatch as the wing mounting holes land right on the edge of the structure. I just did a really poor job. A cutoff wheel and 5 minutes would net results 95% better than what I did. I can text/email you a pic...not gonna post that "handy work" on here
