Hi, new to this forum but have a couple questions. smashed my grill bumper and front passenger fender hitting a buck coming back from hunting, got one with rifle and one huge one with my truck. I have an 03 Silverado 2500hd 6.6l diesel. Insurance totaled it and I bought it back. Appears all damage is on front end, frame looks fine. My question is what years of the first gen have same body parts i.e. fenders, grill and bumper, bed 6',also smashed cowling and airfilter box.
