I have an Grill Guard I'm trying to install on a 2014 Titan. The first photo attached is from the install guide, clearly showing where the top mounting bracket attaches to truck in a perfect world scenario. The 2nd photo is from the inside of my truck, showing there is NOTHING on either side for brackets to attach to. I'm thinking the truck was in a collision? Is this an easy fix, or would I need to get some fabrication work done to make this work?
