Well, we were curious how the 99+ CDC chin spoiler would fit on a 98 or earlier, so we attached one to a 97 GT and we were very pleased with the results. Even though the spoiler isn't made specifically for the year, it matches up perfect at the front, and fits along the sides as well. You would have know that the spoiler was not made to fit that year by looking at it. I'll add pictures to this thread hopefully later today. This is good news because CDC mach 1 chin spoilers for 99+ are very inexpensive compared to the CDC 96-98 ones (about three times cheaper).
