Stunin, your Boxcar is an '01, mine an '02. What I need to know is if the later '03/04 will replace the earlier vents as they have the vanes included and not separate like ours. When removing the later ones you won't have to fiddle with the interior vanes and of course risk breaking them. Also I am somewhat more fond of the '03 over my '02. Thanks for your input anyway.
