First, welcome to IRV2 and to the CC owners forum.
Dust covers?? Are you referring to the rubber gasket of sorts that surrounds the light assembly and fills the void between the light and the fiberglass cut out?
Anyway, some of the Intrigue owners will likely be more help. Also, you can call the folks at CC in Junction City and they can probably help. Finally, there is a fellow named Kevin Waite, a former CC tech, who can get most any CC part you need. If you want to give him a call, send me a PM and I will give you his number.
