So I was going to swap out my broken sunroof with a 99 sunroof, I measured mine and it was 26.5" wide and 14.5" long, and had someone measure his roof for me in his 99 GTP and it was 21.5x33.5. I've never heard of a size difference between the years, everyone's telling me mine could be aftermarket from the previous owner but who would actually spend the time/money doing that on a stock GT?
