Not that it really matters; but that bolt you point to (Chuck's airplane) is
in Atkins' mount plate (made for a 13B), and in the Ross drive; not in the
engine flange (20B).  And having the exhaust go through the prop out where
most of the thrust is being produced may give a performance penalty.

What is your reasoning on that Al? The prop is in the wake of the 
wing anyway.
