Where to find "correct" '67-'68 trunk weatherstrip source needed

Ok, I'm not crazy and I'm getting closer to finding my trunk weatherstrip. I found someone with a restored 65 Newport that has the same style seal (and installation) that I had on my car. Here is the link to his restoration and a couple of pictures of what I'm talking about (how it is glued and wraps around the edge of the pinchweld). Now to see if I can find that same seal in an A-body length. I believe it is actually two styles fused together so it is different across the bottom compared to the sides.
