Good Question !
Have you checked with James Duff Ent, not sure of the site address, but they do a lot of work with Explorers. I know they have great looking front bumpers with receivers hitches, which I was planning to buy but things change, they were working on the rear ones too.
I can't remember if I noticed the flares or not but it wouldn't hurt to look.
Good Luck and post what ever you find for all to read.
