$30 · 1974 Buick LeSabre rear passenger side wheel opening molding

This is a new old stock (NOS) rear wheel opening molding (passenger side I believe) for a Buick LeSabre from 1974,and possibly other years.(76?) Have had this part since when it was purchased(father bought it),and it has sat in the garage ever since.Just recently was able to find the part number on the web to determine what it was from,but the info is not always clear cut,so if someone knows more,and you wish to correct me,that would be great. Part # is 8704428
