If I remember right, he did some cutting as well as painting on that buell screen. I have no idea how he mounted it.
I have the fly screen (or "speedster" screen) that Boxer mentioned. It's a little different, and a little bigger. I painted the underside black (copied from Vann). And used the standard brackets that are for the fly screen.
I was dreaming when I wrote this, forgive me if it goes astray...
