I have a friend who needs rockers and cab corners on his 2011 Dodge 2500 regular cab truck, I looked at the truck Sunday and have never worked on one like that. The cab corners and rockers have no seam in the rear and he said the rockers don't get drilled out at the door flange and said that the new rockers only go half way to the door flange, I told him that the line he was talking about was the stick on rock guard on the bottom of the rockers. Well that is why I am here to ask the guys who know, Any comments are most appreciated.
