the shaft does not have a pedal sprocket. put the shaft through the normal pedal shaft area, and then install the circlips so that the shaft does not slide from left to right. you may need a
small spacer anywhere from 5mm to 10mm for maximum placement of the shaft. slide the pegs on, and make sure that when you tighten them down, the allen bolt on the peg goes into the slot where the cotter pin would have gone. this makes it so that the bolt is flush on the peg, and ends up looking stock when you are all finished!
