yes Ive had to replace mine and the mouldings require @20, 3/4'' rivets. If you dont already have the Z71 package you have to drill the holes for the moulding brackets to rivet into. Without already having the holes there from the factory it would be a PITA to know exactly where the bracket needs to be mounted for the mouldings to fit properly. And these holes arent up and out of the way, they are right under the body of the door so can easily be seen from under side if it wasnt done right. The stock z71 brackets i belive would go right up but IMO without the moulding would look funny cause theres about 5 mounts going to the body that the mouldings hide, you would be better off with aftermarket nerf bars rather than factory if the moulding doesnt go on
