Getting around to installing my dual fan afco heat exchanger on my 2010 and have a question. There are 2, roughly triangle shaped pieces of plastic, 1 for each side with a rubber flap on one side that used to attach to the old heat exchanger mounting bracket with small metal clips. I cant find where to install them on the new setup. I assume they are there to direct air more efficiently so im not sure what to do with them. My instruction book says 2007-2009 and these pieces are not in any of the directions, nor can I find it by searching or watching the VMP youtube vids. Anyone with any ideas or answers for this. thanks
