I have an '05 N* 2wd that I bought in December. I did not notice it at the time (my bad) but it is missing a portion of the interior trim. There is what appears to be a hole where a button like insert in the trim panel behind the passengers side rear seat that says 'air bag" should be.

Can anyone point to a place where I can get a replacement without replacing the entire panel.

Does anyone have a lead to such a panel ?

It is just a plug that says AIR BAG its plastic and you should be able to get at parts department. If vehicle has had carpet removed for leak in rear compartment they have to take these out for panel removal. there should be scew installed in hole to hold panel on.If they have worked on vehicle they may have forgot to reinstall.
