It's unclear as to why Ford deletes the lower rocker cover. I assume it was because I had step rails.
The part for both sides was $222 from LEVITTOWN FORD PARTS. The covers are molded plastic and adhere via the 3M strips provided.

Ordered the mat black emblems from Bronco Depot and am super happy. No more laptop sticker on the side of my $60K Bronco. Broncodepot.com is a little pricey however they provide a mounting template and the quality of is fantastic.
