i just got a monster 1200 r and am getting bar end mirrors. i have read that the threading on one side of the mirror bolts is reverse. i've never come up upon this on any of my other bikes. i will need to remove the mirrors and get bolts a little shorter to hold down the reservoirs. does anyone know the size of these bolts and is one a reverse thread. i figure they're 10mm or 8mm. thanks for your help.
