This was more akin to replacing the wheel covers on a car than it was
to replacing the whole car.

More like taking away the entire car, replacing the wheel
covers, and then bringing the car back.

Pre-1887 1. There is a substance filling empty space.
1887 2. There is nothing filling empty space.
Present 3. There is a quantum structure filling empty space.

Incidentally, the shortening and lengthening effects
that Michelson and Morley were looking for were actually
there but rendered undetectable by relativity effects
of which they were, of course, ignorant in 1887.
