If they are s not to deep you may be able to hammer them out by putting a dolly on the inside and hammering the outside lightly while holding the dolly tight against the back. You may have to use a spoon dolly to get to the areas you can't reach. You can look at them on one of the body tool vendors sights. If they are deep you may be surprised by how much the metal is stretched over all. In that case I would look for a good replacement door or at least one to cut a patch from. It is nice to know that if I take a shotgun blast to the door I am good to go.
