Question for 3rd gen Regular Cab Owners

For you 3rd Gen Regular Cab owners...

I'm curious if the Regular Cab trucks have a flat plastic interior panel that covers the back wall? on a double cab, the back wall only has a fabric acoustic material over the metal that is exposed once the rear seat is removed.

when i pull up the parts diagram for Regular Cab its shows "back wall", it's $600, which makes me think the part im looking at is the back metal wall itself and not a plastic interior panel.

 

wanted to follow up here... thanks to roman.

found it, these two panels will finish the back wall if you remove the rear seats...
one is the lower and one is upper.
