I think the less than 22 degree angle rear window is just fine aero-wise.

Previous debates concerning truncated tail cones (greater than 22 degree tangent line) seem to agree that if placed on a long enough body of a certain ratio (forget exact number) they work.

The real question in my mind, is the Mustang long enough. I have serious doubts, but it could be a matter of scaling.

Old thread - for reference:

Good PDF from the above thread, also mentions 22 degrees, Figure-2 on page 4
