Got a pic from someone wanting to sell a set of rockers. See pic with blue door, and having doubts. I have one I believe is an passenger side original. Not sure it was in back of Bronco for years before I realized the value (Now in rough shape). Can someone confirm pair for sale not a Bronco. Also how can you tell a rocker is driver or passenger, Is there a difference????:? ?:? Thank You, Slim
