I get all the parts to fit dry, and then when I glue them up, things are off slightly. I think the angles have enough play to mess with me? Or I don't allow for the thickness of the glue! 
I had the nose together and didn't like one of the joints so I broke it off and filed it down. I glued it together again and noticed the other side wasn't perfect. Good enough. I filed the fit against the cab all over again and things must have moved a bit. Here's where I'm at. I did a quick file to show how the face gets rounded. It will get another fine sanding before paint.
