They won't really bend your door skins, maybe gouge the paint at the most. It would be covered of course. The mounting plate is the problem, the "feet" aren't always bent enough. You can try putting a little more bend in them and/or grinding the mounting surface in the right spots to help them sit more flat on the door. I also should say I've never bought mirrors from LMC. But chances are super duper good that they sell the same replacement mirrors that the local parts stores used to sell.
