Having just had full length mudguards/ fenders installed on my OCR Team 2003 I have myself added some home made mudguards. They are 3 inches wide at the top, 4.5 inches wide at the bottom and 8.5 inches long. The top 3.5 inches are secured to the inside of the mudguard using 3 rivets with washers. My Dad helped me with his drill and staple gun. Has anyone else done the same and what was their experience regarding longevity? I am concerned they may blow off in the wind but there again I am a bit of a worrier.
