I just installed a 13" Madstad system on my bike today. I also have about a 2 1/2" x 3/16" gap on each side, How did you correct it. Did you slot the 2 outside holes? My real problem is, I think I bought too tall of shield (13") I am no longer looking over the shield, I think, it got late so I haven't taken the bike out for a ride yet. I am 5'11" so I thought I would go to the next size up (13") for better protection. Did I make a mistake.
