I changed out the fender flare running lights which required rear flare removals. You can get to a few from the back side, some can be popped with a panel popper and some I couldn't get to at all (broke those). I found replacements on Amazon though.
I pulled my flares to change the running lights on my 2020 3500 AT4, in the process I broke some of the retainers clips. I've started searching but the schematic picture is vague and not sure it's what I'm looking for. Anybody know the part number and source?
