Kafer65,I took some clear vinyl,laid it against the computer screen,and traced the outline of your proposed mods with a Sharpie.When I put a protractor to the image,I got about a 17-degree angle,from where the roof begins to drop away,and where the boattail ends.I couldn't actually see the end of the tail,as it's cropped off in the image,but I was guessing that it did not project much more beyond what I could see.Anyway,I believe that if you raised the top of the tail and projected straight back,horizontally,the tail would terminate on an imaginary line intersecting at a 12-degree angle with the roof.I think there's a consensus among members at ecomodder that you wont be able to push an angle any steeper than 12-degrees without separation.If you can make sense out of my post about Tiger Woods and Cinderella it will also provide some guidance on workable rooflines.
