Purchased mine off ebay:
Item# 4011070 2001-2005 EXPLORER SPORT TRAC EGR RUGGED SERIES BLACK FENDER FLARES 753334F. You'll need to purchase 2 of these. The front will fit the back
and the back will fit the front. One will say FL Front Left which can go on the back or front. I purchased 1 pair and searched the entire East Coast, contacted salvage yard in Florida but the guy wouldn't sell them. Last chance I ordered another pair and they fit.
