Parts or Repair The frame is tweaked and don't have time to deal with it. 2007 Chevrolet Crew Cab 4x4 LTZ 6.6L Duramax Diesel 150K miles. Just added cold air intake, New 5" exhaust, Y-Bridge, downpipe, 5 position switch for 5 different tunes. Unicorn for this year no rust on box, there is a ding in rear driver corner and above pass wheel well. Leather light gray interior with buckets and rear entertainment. Our loss is your gain. Engine starts and runs, no airbags deployed. Had no issues with tranny/transfer case front or rear end and driveline. Tires are in great shape. Text is preferred for quicker response.
