go to the local supermarket or party specialist shop and get some of those bendy flexible straws, attach to air intake, drill holes in the gaurd and put a cereal bowl (upside down) on top of this - perfect for a jimny!!! no just fooling around - why not try one of those specialist plastic manafacturers
