Hello, I have purchased this for my 2019 Ram 1500 Bighorn Crew Cab truck. The truck did not originally come with this storage bin. When I look at installing this storage bin, it appears I need to remove the interior trim pieces around the base of the rear seats, but these pieces will not go back on after I install the storage bin. Is there a different trim piece I need to use when installing this storage bin? Do you have installation instructions for the storage bin you could send me for upgrading a 2019 Crew Cab without the storage bin into having the storage bin? Thank You,
