I've been toying with the idea of fitting a 65 grille to my 76 CBII. So, I ordered a repro from Mustangs Unlimited and took my dremel to it. The fit is a little off, so I made a cardboard patter of the curved ends, then traced it on the grill for the cut lines. I made a plywood buck from the same template and formed the flange on the grille to the shape of the opening. All I have left is to solder the ends of the flange along the lap and mesh edges, then mount some turn signals. Haven't quite figured out what to use for turn signals, but was thinking of some small amber LED lenses. Here's a pic of my unfinished experiment:
