The grill came with the truck, I think it's part of the Ivan Stewart package. As far as the ammo box, I drilled 4 holes through the ammo box and bed, then used 2 rectangular u bolts with the nuts ending inside of the ammo box. It worked well, but I ended up removing the ammo box and welding up the holes in the bed. Everything fits inside of the UWS.
I've done some small things here and there. Finished the air compressor install, but would like to fab up a water/mud shield. The digital gauge works well, but it doesn't dim so it's a little obnoxious when driving at night. I'm in the middle of using a scrap piece of 1.75" tube for a fire extinguisher mount. This will bolt to the console and securely hold a 5 lb extinguisher. Added the udnerhood LED lights also. Certainly not needed, but helps when the sun starts to set and I'm still doing something under the hood. I haven't been happy with the location of the fuse box, so I will be making a platform of sorts and mounting it horizontally. My girlfriend isn't a fan of the sliders, so I welded a piece of metal over one of the openings to step onto. I made the first bend for the bed rack, just a test bend. Lots to go, and unfortunately I'm stuck working in the ICU so I have very little free time.
