mud flap rear

help im getting in a flap about my flaps ! ive just bought some rear flaps for my 110 county and i have no idea where to site them under the beast can any of you guys or gals help me out i must add im a complete novice at this but a keen learner
thanks

heya i spent some of my work experience with my face in the wheel arch (working on the rear crossmember). i think they are bolted to bracket thats just inside the rear of the arch. if u take a picture looking up into the area behind the wheel arch, i might have a better idea. hope it helps Ross
