It seems that Mercury only sells plain "flat" mud flaps (splash guards) for the Mariner. However, in addition to the "flat" mud flaps, Ford also sells "molded" mud flaps for the Escape. I really would rather have the "molded" style because they look more custom, and integrate into the flow of the body contours nicer.

Does anyone know if the "molded" mud flaps for the Escape will fit the Mariner???
