Good used driver side (left hand) driver grade quality bezel with minimal, light pitting, ready to install and use as-is. If you are planning on sending in cores to be restored this is the level you would want to start with. The pitting found on this grade "B" bezel will be light and almost entirely restricted to the top surface which means it will only be seen when the trunk lid is opened. Driver side chrome tail light door or bezel.
