Can someone who has done it share some info?

I've removed the 4 top push in peices, along with the 2 screws (when the tailgate is open) along with 4 or so push in pieces underneath. The fender flares have 2 push in type things too. It's still not loose and I don't want to break anything, it almost looks like these things in the picture need to be released or come out or something, but I'm not sure.

(All technical terms referenced above are trademarked by me)
