The West Coast mirrors that Red58 posted the picture of are the right idea. The picture looks like one from a big bolt though. They did make a smaller set for pickups. My dad had a '60 three quarter ton and the chrome West Coast mirrors looked really cool on it.
I can also remember building plastic model pick up kits back in the day and they included chrome West Coast mirrors.
I definitely like them way better than the big squarish rectangular mirrors. My '59 panel came with one of those on the driver's side and that's the very first thing I took off of it.
