I'm doing some mods on my 900 Custom and have always disliked the big gap between the rear fender and tire. Does anyone know if a Classic rear fender will fit? I realize they bolt up in the same place and the chrome trim pieces will fit, but the turn signal mounting area and the back part of the seat are different. I suppose I could just go to the dealer and look, but was wondering if anyone else has done this before. Thanks.
