05 mask fly screen

Hi gents, I've tried searching and can't find the answers I need. I'm looking for a fly screen for my 05 sd but all the screens I find or mods to change mask are or 06-07. My mask does not allow me to fit a fly screen and at the end of August I'm going to the BSB round at Cadwell Park which is a fair joint from where I stay near Knockhill. All help or recommendations welcome
Thanks Ali

These guy's have some ,,,,,,
