ok, since you have a '97, OEM is not an option....OEM fogs for '96-'98s were discontinued years ago, and are nearly impossible to find. You could maybe find them used, but new ones are going to be a pretty big feat. There are a number of companies that make replica oem (both square and circle) ones for your car, although the quality of them is questionable at best. The only half way reputable company that I've seen that makes those replicas is Pilot...but they only sell the circle ones (which in my opinion are ugly).
