I know on the older chevys you could, I’m not sure on these newer GMCs. You could always pry gently on each corner and see if theirs any wiggle room, if their is, then you know it’s probably just held in by clips, and not bolts
Question for you. Did you run into any issues during the reinstall? I’m working on my ‘23, and the latch doesn’t work from inside the cab. I cannot push the rod down.
