Can anyone i.d. these for me?

This in the one on my car (which really needs a bath)

So I maybe wrong…

Those are the 1973-'80 "universal" indicators. 1972 & older units had no exposed fasteners. What's different about the ones @67Dart440GT has, specifically, is their length and recessed lenses. The standard 1969-'72 indicators used on everything else (except C-body/Imperial) are similar to his, but they're shorter with a flush lens:

I would love to have a set of the ones in the original post for my Challenger, even though they're incorrect. It's a '74, so it came with the exposed-screw type like what you've got.
