Thanks guys.
Pete, you are correct. Anyone trying to add new windows should be real careful not to remove too much aluminum material during the Dremel or flat file steps. It took me about 1-hour per window.
Even though I finished the window edges straight with a flat file I still ended up having an issue with the paint on the window edges. Look at the front window frame of the bar area and you can see where the thickness of my Armour yellow paint is making the vertical edge look wobbly. I should have thinned down the yellow paint before applying.
I did not find this painting mistake until after all the clear plastic windows, inside wood wall paneling and curtains were installed and was examining the close up photos.
