The 450 side covers have many differences from year to year, but all have two flat 'male' tabs on the top that fit into 'female' slots on the frame, with rubber grommets. In the middle is a screw that screws into a skewer which goes through and holds the airbox/filter/ badge together.
Anything can be done, but it may take welding on the frame and other mods.
This version has a 'v' stamped into the side which used to help locate a badge which they eventually did away with and smoothed out. It also had two holes that hold the badge, about 2-3 mm diameter and it looks like they smoothed those out here. The pins on the plastic badges all break, so just the screw and two sided tape is what I used to hold them.
I've got extra pairs of these if you want some, and others, that would all need paint or tank painted to match, holes filled, etc.
I like that they are metal, they dent instead of shatter.
