Well, surfing craiglist for an ARB finally paid off!! I found a never-installed bumper sitting in some dude's garage for less than 1/2 what a new one would cost me! I was pretty excited to bolt it on, and I was working in poor light after dark, so I didn't get any pics of the initial install. I did snap one yesterday at work:
Though I'm happy with the function of the bumper, I think ARB could have done a better job with it. First, it is HUGE. Like almost too big for the truck. If I bolt it on using the intended mounting holes, it sits WAY high on the front of my 2500HD GMC, and the grille doesn't fit. I think the Chevys might have higher hood lines, and hence higher headlights, grille, etc, but it looked dumb on my GMC mounted that high. And the grille didn't fit because there's a black filler piece between the grill and factory bumper that would have needed to be removed. I lowered it about 1.5" and it is looking much better, though still a little high. The bumper now sticks into the wheel well a bit too at the top, so I'll likely do a little trim and re-weld on that and get it looking proper.
Unfortunately, one of my co-workers is borrowing my truck to move, so I won't be tackling any mods this weekend, but it's getting the 8274 that I have laying around as soon as I get it back. Little plasma cutter work to be done, but the structure should be plenty strong for the 8274.
I'll post pics as the mods get done.
