Thanks for the pics.
Although one pic is shot from a higher angle and the other
appears wider, it gives me an idea at least. It is not a bolt-on fit
as someone already said.

The critical areas are the distance between the grill and the side of the
headlights. It's easier to remove material than to add it back in. I have a
way to do that, but then my concern becomes the alignment of the hood
crease at the side of the grill and the path it takes as the crease starts from the grill
and goes back toward the windshield. To overcome that I would make a custom grill
to fill the available opening.

Another area of concern would be as to whether the wheel well radius as
seen from the side can be made to match up from the metal fender as it
curves down to the plastic of the bumper.

It would be nice if we had the newer bumper cover so we could make some
templates and see how well the templates match and if it can be made to
work or not.

If it were my own car, I would buy the newer bumper cover that I wanted to
put on, and if my measurements showed that it would not look right, I would
just return the newer bumper cover and get my money refunded.

As for the bumper fitting the car, the lip on the bottom and the grill being
chromed or black is not a factor related to whether it fits or not.
