I received my Madstad Thursday. I had quite a bit of trouble getting the ends of the base to mate to the fairing. Old and new wellnut's keep popping out at the outer edge. I did hold it in as I tightened the screws. I talked with a fella at Madstadd yesterday.Forgot his name. Mark? He even called me back after talking some measurements on their end. My opinion is the base is not curved enough at the outer edges, plus the wellnuts shaft diameter are just a little too small for the holes HD has in the fairing. That is HD's fault not Madstad's. The oem screws are also on the short side with the thicker shield and gasket. They are sending me out a new base Monday, that he said they will curve the outer ends a little more. Very good customer service so far. Any one else have this problem? Stay tuned.
