I hade the ebay ones for 3 years now it was time to stop seeing elbows. I custome made some adaptors out of 1.5 in delran I had at work. I couldnt see right behind me so I had to add 1/4 in spacer on the front bolt to position the mirros. Now I can see behind me. Now I just need to make a filler plate to blend into the faring after the season is over.
