is the 300 zx bbk still available. if so will it bolt on to a 98 maxima and are the rotors and pads used or new. if used how worn. Also interested in the cattman y-pipe. what condition is it in and how long was it used for? does the magnaflow ehaust have the brackets welded on for the maximas. also how much to ship to 11767 (NY). thank you for your time.
