Peter, I love that blue and the GT/CS is a great pick. I have a GT/CS rear Fascia on my '07 thanks to a Camry, ironically

I have a red '68 convertible as well that I love to cruise but push come to shove I love DRIVING my late model more. I push it harder and faster than the old one because that's why I bought it. Even with an upgraded clutch it is a fun car to drive frequently. Welcome to the Mustang family you dove in head first!
