Nevada side skirts/boot spoler

I have just bought a 2003 “Nevada” and its fitted with side skirts and a boot spoiler which the insurers have taken an interest in. I can see from an earlier bill that they were removed and refitted during a refurbishment but can anyone tell me if these may have a been a factory option or must they have been an aftermarket fit.

They are definitely after fit, can’t remember if they were actually a Mazda branded option.
The Nevada didn’t come with any of that including that front splitter, all added later.

My MK2 import got fitted up with skirts and a boot lip after it arrived in the UK.

Thanks, I was coming to that conclusion after being unable to find any official pictures from Mazda showing these on a Nevada.
