delivered through a dealer in the United States. Port-installed options
provided by the factory are considered to be the same as
those installed on the factory production line. Dealer-installed options
or deletions (except as required by factory directives), no matter
how common or what their origin, are not included in this definition.
This definition does not allow the updating or backdating of parts.

You just made my point. There is no factory-provided part here. Again, read the quote in blue in the above post. There is no such thing as a factory-installed rear sway bar on a US Yaris. The rule you quote clearly states that a factory-available part can ALSO be installed at the port instead of the actual factory and still be considered "standard."
