It unfortunate that the italeri superliner is so inaccurate. The aftermarket , especially Auslowe, has made parts available to make the truck more accurate with options such as Mack air cleaners, crossmembers, suspension, engine and gear box options. Us Australians are lucky we have aircleaners on our superliners as it covers up the inaccuracy of the italeri kit pretty well. Hopefully italeri will do an accurate new American truck soon. At least the aftermarket caters pretty well though.
