Brush Guard Install???

I have a SuperATV brush guard for my 2015 900 Trail RZR. It only takes five bolts to install. Simple? Should be. Two heavy duty bolts from the inside out screw directly into standoffs on the guard. Three smaller bolts go just be low the winch area. However, it seems to me that the only way to install the two main bolts is to remove the radiator. There is a cowling around the fan area and no way to get your hands, let alone tools back there. I have tried several different ways to get behind the plastic but without success. If all else fails, I will call SuperATV Monday and see what they think. Just thought someone brighter than me might have the solution.
