Most people in the know seem to say these doors are all from the same maker and just re-boxed by different brands. I believe Dynacorn is the maker and even GM approved parts are still Dunacorn. I personally bought doors about 13 years ago and they were horrible. It was a lot of work to get them to fit. That said, things may have changed. If I had to do it again I would get original or cut down some original truck doors. One of the areas I had the biggest issues was where the door met the rocker. Had to cut 1/4” of the bottom of the door to get them to fit. They never looked right where they met the windshield support either. I would make sure you are ready to fit them with the rocker on so you can return them if needed.
