newbie looking for some answers on best Demon quarter panel

I am in the process fo replacing my full quarter panels and having a difficult time getting the lip at the door jamb line up properly. I don't have any pictures of the fitment but it appeares that the top is pulling the jamb back and it is causing the bottom of the lip to go forward. It also seems too tall in that area. I am about to give up and have a shop do it. These are AMD full quarters.
