So in the big book and, on the mother ship web site, it clearly states "Will not fit the Tri Glide !" Wrong in so many ways. http://www.harley-davidson.com/store...oard-mount-kit 50500403A They fit perfectly. The change over let me lose those ugly looking, get in your way calf killers Harley uses for passenger floorboards. The mini floorboards with their black body blend in against the side covers nicely. The brackets allow one to use fold up pegs too should that be one's choice.
