If that grill is all in tact and in good shape you might throw it on ebay and see who bites! I have seen some fetch as high as $1500 since they are hard to find and very fragile. Most are broken from leaning over the front of car working under the hood.
I have used them a number of times but my advice is to call the yard don't e-mail them. I didn't get any response 90% of the time when I used e-mail to ask about parts.
LKQ is a salvage yard that sells on e-bay and has outlets in several cities. I live in Speedway,Indiana and there is an LKQ in Avon, Indiana just a few miles down U.S. 36 or Rockville Road to the local folks.
