Thanks for all of your input. Brad, I really like your suggestion of just putting in the corner windows and not the whole outer panel. I appreciate you taking the time to post the pictures and keep me from " reinventing the wheel " on this project. This is my first attempt at a project of this size, so I want to keep it simple and not get frustrated by botching it. I will just take my time and get there bit by bit. Thanks again to all of you for some great advice.
