I know the guy who had the Lat42 MudFlaps got out and sold the biz to 3sx recently.
I was lucky enough to get a pair of the rears before he went tits up.
Not a whole set with hardware and all but just the flaps for a reasonable price.
I must say, they are incredibly easy to install and look great, not noticeable, not blingy and add that "just needed" view from the rear.
I know they are pricy from 3sx but damn, well worth it IMHO!
