1968 Barracuda Tail Panel

Hey guys, I picked up this 68 barracuda a couple months ago and the tail panel trim was not installed. It came with the 68 trim as well as a 69 trim panel. My question is regarding what seems to be an excessive amount of holes in the middle portion of the panel (see photos). Is there some kind of piece that goes in the middle on a 68?? I assumed it was just the body showing through. Clarification would be helpful. Thanks.
