not sure on yours because i have never worked on one. but most are simply held on by screws on the front, and some from the back. some may not be accesable( if thats spelled correctly

) but will be by removing the battery and anything in the way, most held in from the front are held in by clips etc that screw out from the front and you can just pop em out. just look around and you'll find em, if not on the front which i know not likely, they will be held in from the back then, not sure on that model, i'm used to either the caprices and or big silverados etc. most likely it's from the front, you just gotta look good because they will be tiny screws. or they might be recessed.
