So the previous gen Silverados and Sierras with bench seating had these pockets on the under portion of the dash. Whether for storage or an ash tray:
Our current gen has this blank piece of soft plastic. I thought, man, they could have really put some storage there. But if you remove it, you'll find there really isn't any room for storage behind it:
So, picked up this. Its a mesh pocket from a Honda S2000. Its mounted on the passenger side of the transmission tunnel:
A little modification to the pocket's mounting clips and 4 small holes drilled in to the panel and viola:
I mounted them using short machine screws and bolts. They sit nicely behind the panel's mounting clips so they clear the stuff behind it when reinstalling:
And here it is installed:
And here it is with a few things put inside it:
Very easy, simple, and inexpensive mod for anyone wanting a little something extra in that region. For me its the perfect place to stick my phone when its hooked up for Android Auto since I dont like my phone sitting in the top dash tray cooking in the Florida sun. I also frequently use the jump seat (family of 6) so I dont always have the arm rest area to use.
