Got all the screws out from the sill and under car areas. Also removed hidden screws under emblem. Manual says to pull out and rotate up to remove piece from clips at rear of body. Tried that and afraid I’m going to break it. Any trick to removing this??

 

Never mind. There are no clips. Stud inside car with a speed nut on it. Info coming from GM Camaro Service Manual. 😡

 

That’s correct. You can get to it either by removing the speaker, or if you (or a helper) has small forearms, remove the vent in the door jamb and go in that way.
