Hi, I recently picked up a new 2015 ranger 900XP. Saaaweet machine. I just bought the upgraded a-arm guards. Just went to install the fronts and the first step of instructions state to screw off the existing small OEM guard. The thing seems to be bolted in with steel pins (no screw tops) that I cannot figure out how to remove. Anyone encounter this? Seems simple but this steel pin is strong and tight and not budging.
