Just unscrew them from the stock fender and re-screw them in the new fender in the holes provided on the sides. Only goofy part is that the stock blinker has a smaller bolt and then wires, whereas aftermarket blinkers usually have the wires running through the bolt. Or if they dont fit in any of the holes you could always take your reflectors off their brackets and just screw your blinkers into there. I hope that made sense. I could draw a pic if necessary. Hope that helps...
