What's missing.

Newbe here. While harvesting information here, I came across a thread from Bobacuda concerning his battle with seal replacement. I copied one of his pic's because it highlights one of my questions about the factory trim and the distinct possibility that I won't be able to locate these pieces.
What are these missing trim pieces called, and does anyone have any idea where to aquire them.
I really appreciate the info if your in the know.
Yes, the gap really bugs me. 67 ragtop.
