Not in the office/workshop right now (More on that later) but although the lack of symmetry has never been in doubt, I'm not so sure as to what is causing the wheels to be outside the bounds of the arches. The following photos show a Pilot with a Navigator bonnet and a Navigator with it's native bonnet from both sides and you can see the wheels are well within the arch boundary.









Note too that the Yellow car has an early Navigator bonnet which was laid up before the arches became 'rounder' and less like 50p coins.
