just had the same issue with a 69 swinger 340 stripe delete car. The previous owner swore up and down that the side molding was factory. it was the ugly squared off metal trim with the plastic insert. I looked for any indication or proof that he was correct and founnd none, so decided to go with the stripe. I origionally planned on filling the holes myself, but being a novice, and realizing the damage i could have done with the welder, i paid a ton and had a pro do it.
