Jim, I did mine in about an hour and a half. I did end up trashing the slide strips that came with it. When I tried to adjust the shield, they got caught and tried to bunch up. Have had no problem without them.
Make sure and cover the Honda hole under the mirrors while removing hardware :!:
Don't ask how I know you can turn this 1 hour job into 3 hours. Lets just say if you drop something down there you get to take lots of things apart to find it. It turned into quite the learning experience.
