Personally, I think you're doing it right, autoguy. The decal logically needs to fit the inner-most part of the recess only, because if it were a true opening, that's the area that would have a consistent shading. Upper and lower edges wouldn't look the same because of their angled surfaces.

And a question, autoguy, any plans for side stripes, such as for the quarter panel arches as below in fixxer56's sig. picture? Since I'm getting the Ralley Stripes I'd want something rather narrow so the combination wouldn't look overdone.
