Challenger Glovebox Lock Mech

['ve purchased a new locking key cylinder for my 70 Challenger glovebox from classic industries. I cannot figure out how the keyed cylinder goes into and out of the latching mech. Can anyone tell me the trick for installation/removal? I managed to get it into the latching cylinder and now I am stuck. Thanks

Paperclip in the hole trick I think? I did it once years ago. Clip goes in and then turn the chrome bezel at the same time???

I believe you need the key while doing this work.
