Not to be mean, but you probably won't find one that lines up "perfect". These things were not the most quality controlled when they were made new. Yours is actually in really good shape, other than that one kink at the top. Most of the ones I have seen that are decent never fit perfect around the outside/to the fenders of the truck. If you are willing to get the bumper chromed and worked, you could probably get the grill done the same way. This would be the only way to make it as close to fitting perfect as you are going to get. Bad part is one bouncing rock and it will be chewed again as these are not the most sturdy pieces.
