Question on side molding '70 Duster 340

Hey fellas, long time no see !! I sold my car to my youngest brother a couple years ago, and I'm trying to give him a hand restoring her...

The build sheet lists "stripe delete" and when I bought the car in 1978 it had a vinyl molding down both sides and a striped across the rear between the tail lights..

It sure appeared the molding was on it from the factory as most of the paint was original when I bought the car..

I've only seen pictures of a couple with it, and trying to verify that it's correct, and if anyone has a source for new ones.. Old ones were taken off many moons ago...

Thanks in advance fellas, and hope all is well !!!
