Wheel well trim/ fender skirts
 

Look for a place to buy wheel well fender skirts for 22.5 wheel.
Something like this

I wonder if you contacted one of the large builders, Showhauler, Hawk Engineering, Renegade, etc....?

Curious as to why u r looking if u don't mind me asking?
Like the look of it, function or ?

im betting theyre custom / rolled - a good (custom) body shop should be able to roll a set
