unsilenced air cleaner diameter

anybody have one they could measure? the outside diameter of the lid is what i would like to know, as well as the filter diameter. my air filters will be stuffed up into the scoop, Hemi with a crossram, and living in the Pacific Northwest we do get some out of the blue sky rains and am wondering if i could squeeze a pair of them onto the throttle bodies....or if anybody has some suggestions beyond this thing for $2K.....
