Can the shape be simplified to being just a curve? That would make manufacture easy. Just cut up some tubing and install at an angle. I am guessing it *does* need the "fatter bottom", because it looks like an airfoil.

I was looking at Abbott and Doenhof's airfoil book and I wouldn't want to presume that any change to what Ford wouldn't render a failure.There are so many different airfoils and their performance varies with any change of angle-of-attack,that if I was going to attempt this Lameller grille,I'd follow Ford's proportioning religiously.Without a good windtunnel it would be near impossible to anticipate performance.Maybe CFD.Don't know.Airfoils are extremely labor and time intensive fabrication projects.
