If you look at cars from the 20's & 30's you can see headlight placement is all over the place.
Jeeps still have 1930s-style headlamp placement. Now, they're required to mount the yellow running lights more outboard, but from a distance, they're stiil closer than they appear.

Every 25 years I like to rebuild that 292, whether it needs it or not.
