Door Lock Grommet help

so i bought some anti-theft door locks for my dart today, should be here next week (gotta love ebay). anyway i notice my car has no chrome grommet where the lock knob is. i dont have a car to compare, but it seems obvious that there would be a small piece of chrome to sperate the black door with the black knob. if anyone can help me find this grommet id rly appreciate it.

i have a pic below of what im tryin 2 talk bout, sorry for the poor quality
