They are readily available from AS store or dealer. When I had my 2007 in for replacement of the rear upper sections, the identical one to production was no longer available. The replacement was less gray and more silver. I noticed the difference after I got home from JC and called the service center. They sent me the matching one for the front....NO CHARGE!
They are as Jack describes and easy to install.
