Recently added the South African style mudflaps. These came from CP1 Imports in Vancouver and come with very poor instructions for the front set and no instructions for the rear. The front set use three clips to hold the flap to the wheel well. I was very sceptical about these clips staying in place on rough roads. So far, however they have not fallen off, even after travelling about 25 miles over very rough logging road. I may still, use some silicon or epoxy to reenforce the holding power of these clips for my own reassurance.
