Question on side molding '70 Duster 340

I bought a 1970 340 duster off the showroom floor that had stripe delete and side moulding. It was an oddly optioned car in that it had a two tone paint job with black on top roof with the vinyl top trim and orange body. It was ordered with the deluxe steering wheel which included a factory tach. It had a 3 speed on floor with 3.91 sure grip. Last it had a go wing and white wall tires. So yes they did come with side moulding but I expect it was rare.
