With mine they are very close. You could oval the holes out and they would work but i wanted mine to look like they came on the truck so i took my time and made a template because it wanted the mirror to follow the body line. if you just oval out the holes the mirror will not follow the body line. Also once they were just held to the body i noticed that the mirrors were going to sit up at an angle sort of like what the towing mirrors look like on the the 2000 model chevys so i trimmed pieces of plastic off so they would sit flat. It's all on your personal opinion if you dont mind them not matching the body lines and sitting up at an angle then they are very easy to install
i like your addition of the dodge mirrors, do those fit directly on or did you have to mod them?
