New style Kappasphere that will work with an XM radio antenna and a rear wing. I took this off of my Solstice but believe it will also fit a Saturn Sky. It has had minimal use and is still in good condition. The chrome still shines and does not look bad aesthetically when I have it mounted. I am asking $150 OBO with buyer paying for shipping. I live in Atlanta(zip code 30324). Please let me know if you've got any questions.
