AM/FM with 8 track. Originally an AM but I put a Am/FM in so I can use my MP3 with an Transmitter. And AC. If your not checking the high performance box why not have the creature comforts. Power windows, With the convertible this should have been a mandatory option. 400 would have been nice just to get the hood but the 350 is fine for everyday. But as a hole wouldn't change a thing. I built it. Its mine and I have not pulled up next to another one yet.
