do you know anyone who is a fabricator,because ol cheap skate me got an oval shaped air cleaner element from finer filter,which was about 100 mm tall,then got a friend who works in the model shop at a leading white goods manufacturer(alright,fridges & washers),to make be a base & a top to suit.this gives enough clearance to use the ram tubes,& looks pretty cool,actually.just use 8mm threaded bar on the two inner bolt holes of the su's to mount the cover.damn,looks like i'll have to fire up the digi camera & takes some photos.
