I will check the part number when I get home, its on the invoice. As someone mentioned previously in the thread there are two parts, a cross member up front then the actual skid plate itself, You have to drill two holes on each side for the crossmember. There is another hole that gets drilled in the tubular frame cross-member next to the stud where the fuel tank strap attaches and another hole near the hanger for the e-brake cable (which come off) that is in the drivers side wheel well. I wouldn't sweat drilling the holes, they (DC) drilled them for the TC skid plate and would have drilled them for this plate as well. There are some existing holes that "look like" they are for the fuel tank skid plate cross member but they are not as they are way oversized/one side is missing a hole, etc. When you get the cross member in place you will see that the actual holes are and inch to an inch and a half above any of the existing holes.
I will see if I cen get some pics tomorrow. The "skid plate" one on my 1500 offroad was plastic, this one is fairly thick steel plate about 1/8", not sure what gage. The thing is fairly well skeletonized to lighten it, but this might me a bad thing as a pretty decent sized stick could still poke a hole in the tank. Also the cross member is defenitely not strong enough to support the weight of the truck. Just for fun I threw the jack underneath of it, it will bend fairly easy if the load is in the center.
I paid about $260 Canadian from the dealer.
