I am trying to determine if certain parts on my 2005 have been changed out. They just seem to be out of place. First, is the front frame cross brace (one above oil filter) mat black to match the frame or is it gloss black? Also, are the upper and lower tanks on the radiator mat black or gloss black? One last thing, shouldn't the last six of the engine number match the VIN? Thanks in advance for any help guys.
