I am guessing this may have come up before but I searched and could only find discussion on shortening them.

Has anyone put any kind of "finishing ring" around them. As they are, straight from the factory, just holes in the door panels, they really look like something was overlooked and is unfinished. I looked at the ones on the Cobalt and they may work though I have not got a clue if they can be ordered separate from the door panel (have not had a chance to poke around GM parts online, nor ask my dealer parts dept). Chrome ones matching the actual butons may look nicer and a bit more retro but anything is better than those holes.

 

NF-
I'm unaware of anyone doing anything else (besides shortening) to the door locks/holes. Agreed- a hole in the door panel is a bit plain, but, most who changed were concerned with arm comfort when the windows are down.
Be sure to post pics if you mod yours!!!
