Ok, I hope this comes thru. What I am going for is the back 8" of my project for now.
When viewed from behind, I used arc and elipse to get the shape. (The final size from the back will be 5"x1.9". The front view I drew for 7" forward where the size will be 3.5" by 1.5" From the top left edge I slanted 2.5 degrees toward centerline toward the front while the bottom left slanted 11 degrees toward the front centerline.


After I get this figured out, I will move to the next part of the project and learn how to shape it.
