Help fixing a dumb mistake..

In one chapter of my book I mistakenly started on the Left Page instead of the Right. Of course I then used that as a template for 10 more files in that chapter. I didn't notice it until I went to create a TOC for the first time in the project. Every page has tons of icons, graphics and tables, several of which were "manually" placed. So it would not be a simple copy and paste to go through all of these in a clean template. Is there any easy way to make a Left page Right, and a Right page a Left, because of course my margins are different inside and outside and the first page of each section needs to start on the Right. I realize I will still have to go back through all the page and tweak some of it, but that would be better than re-creating them. I really hope that someone know an easy way to fix this...
