Vinyl Top Molding "End Cap"

I just had someone on FB ask me if I have the “end caps” for the vinyl top trim molding set I have for sale. I’ve never heard of these. Does anyone know what they are or have a picture of them? I always thought the molding was just the four lengths of trim.

Here’s a link to the post in question so you can see the pictures of the set I’m selling. Am I missing something?

I have never heard of vinyl top end caps. When vinyl top cars were made they had another trim piece that was installed over the vinyl inside the drip rail on each side of the car. I don’t know the official name for these pieces but maybe that is what the person was referring to.
