I have the razo pedals...love them. Anyways They came with the pedals, a backing/ metal plate to the pedals (this is what connects the straps and the pedals together), and the metal straps that wrapped around the existing pedal.
1) I attached the metal straps to the metal plate 2)I had to use 3m tape that was provided in the kit to stick the metal plate to the existing pedal. 3) wrapped the strap around the exhisting pedal. 4) screwed in the new sport pedal. Took me about 30mins to do the pedals and the dead pedal. These instructions aren't exact and as detailed as the instructions given, but hopefully is helps.
