Finally got around to looking at the paint code, if my searching is correct, it is called Dark Tarnished Silver. Unless it is a 2012 Cadillac, then it is Silver Smoke.
I found it in the spare tire well. Or on this model is it call, fix a flat well. :-) Not sure if this mode had one on the trunk. Long ago, my wife got hit and it was minor but the trunk lid was replaced.
Other than a few clips, it not going to cost anything to try and put the old one back on.
Anyone running across this thread, here are the clips I found for reference.
The white one is Amazon.com
The black one is Amazon.com
