I sold my 07 (GMT 900) Z71 and still have the wheels and tires. They are Pro-Comp 18"x9" wheels, with Dick Cepek FCII 305-60-18 tires. They have about 10k miles on them. Cost me over $2500 new. Comes with center caps and locking lug nuts. First $1100 takes them. I would entertain trading for 99-04 Mustang wheels and tires. Must be 17" or 18" x 9" and 10" (staggered). Let me know what you have. I also have a custom tuned PCM and TCU for this truck (GMT900, newest body style 5.3 motor) for $225. Air Raid intake tube - $80 Cover King Seat Covers - $125 Thanks, Ron
