I used aluminum L stock to make the V. Screwed into the ply... not a big deal ... if you take them out later a dab of white silicone and a repaint will hide them. I bought 66" x 4" of 1/8 aluminum. Clamped half to my table saw top then sandwiched the other half in-between 2 boards (clamped) that way when you make the bend in the middle, it comes out straight. I pre-drilled the L stock so, after installing on the overhang, I could clamp the wind foil in place and then mark the holes to be drilled in the wind foil. I used very small stainless screw and nuts. puts a coat of paste wax on it and the bugs slide right off!
