70 barracuda rear filler panel?

The tail panel and rear trunk pans were in the process of being replaced when I picked up my car, but unfortunately the guy did a massive hack job, and I just dont think I have everything to put it back together with. He butchered the tail panel so I have to get another one, even though its new. My question is, is there a "filler" panel that mates up to the bottom of tail panel, and attaches to the outer corners of the trunk pans, and then the rear bumper brackets bolt over the top of it...
