Not sure what part the bezels are, and can't really tell for sure from the pictures, but it looks like the grill is the same with as the hood, it's just the parking lights that are too wide.
Could you use MM/D-50 parking lights instead? They seem narrower. They come in orange and orange/clear configurations. The latter might work for this.
It might look a little off, but then again, doesn't this whole rig look a little off?... (in a good way)
