''I'm going to fix it up someday'' The resurrection of a '74 Dart Sport......

Thanks for asking, Thunder.
They are original Mopar ones.
The chrome ones are very noticeable and the painted ones are more subtle.
I prefer the painted ones, and you can get them from P&G Classics, but they're not cheap. I hear the chrome ones have issues with the chrome quality and pitting easily on the reproductions.
The originals are known for the top part being floppy and all there is holding them on is a relatively small screw that you tighten and it removes the slop.
The quality of the chrome on the originals seems to be quite good.
