Yup, I had a factory side-molding '70 Barracuda that was entirely original.
They were an adhesive molding, with a stripe surrounding it.
The moldings on the car for sale are the aftermarket riveted-on type that dealers used to add, and had a vinyl insert.
Lots of 1/8" holes would be drilled in the car, and the aluminum part of the moldings - with chrome end caps - were pop-riveted to the car.
