Everyone is right, the installation instructions are not good. I stripped a screw head because I removed it so many times. Does the leg supports go on top of, or behind the guard? I found photos on the net showing both, on top and beind the guard. The instructions don't say. I put mine behind, less triming on the plastic. Yes everyone was right about that too. I will wait until after my next crash to see if I will recommend this product.
