71 Demon 340 tail panel blackout graphics

Hey guys got a question on 71 Demon 340 tail panel blackout graphics. Was the factory tailpanel blackout one piece or two? It seems like all the repros I've seen are two pieces - an upper part and lower part. I do not ever remember seeing any seams on the outer tail light striping..Is there a reason for the two piece repros? Does anyone offer a full one piece tailpanel blackout?

Thanks much!
