Hope someone can help me. I purchased a Smittybilt XRC Gen 1 front bumper for my Jeep JL. Smittybilt makes the Gen 1 and Gen 2 for the JL. The Gen 1 was such a great price I went for it. There are no installation instructions and I cannot locate any on the internet. I get 99% of what to do, however, these were in the box. What are they for?
