68 Barracuda trunk trim

The 2nd owner of my 68 for some reason swapped the taillights and trunk trim with a 69. I replaced the taillights back to 68. The trunk trim is a bit harder to find. Is it one piece or more? I saw what appeared to be upper and lower pieces of trim advertised but was not sure if this id how it should be. I know there are adhesives to go in between for match the color, but wanted to be certain how this works.

thank you
