Installed the steps and bolted in place. There is no way to completely remove the burr that is created when drilling the bolt holes, and this does a number on the primer on the step. Didn't seem to scratch into the metal though so I will just touch up the primer as mentioned in the instructions. Once the baggage floors are in place this becomes an inaccessible area unless you want to drill out a ton of pulled rivets. Some people have apparently used nutplates instead but I can't imagine spending the time to do that.
