I bought some clear acrylic sheet and was going to fabricate some kind of Kammback following the guides here but then I got lazy. I just eyeballed it, drilled some holes and put in some rivets... The acrylic cracked a bit when riveting but hasn't gotten any worse since driving. Rust will undoubtedly form at the holes too... Works well enough for me but I don't know what effect it has on fuel economy yet.
