Ryan,
My NOS fairings came with a translucent blue film which appeared to be sprayed on as a protective layer. They came in a Cessna cardboard box as a complete assembly with the mounting plate, scraper, and trim pieces attached.
Bob,
I made the incorrect assumption that the 0441143-14 was for the wider one piece trim because
Yingling Aviation only listed one "strip" when I entered "0441143" in their search function. Now I'm wondering if that wider trim which I pictured on the white wheel pant is an owner-produced part. Frankly, it's better made than the two piece strips on my NOS wheel pants. Looking at images online now I can't find another example of this strip being one piece; they're all two sections.
That was nice of Cessna to share those blueprints. I'm expecting all the "originality nuts" to soon add the "No Step" stencil to their wheel pants.

Cessna neglected to do this on occasion.
This guy could make you a nice set of trim strips.
