1970 v 2013: How the Darts Stack up

Is 1,000lbs official on the tow rating, before the Dart was officially listed on Dodges website I looked and had to go to a midsize car to get any tow rating, my heavier treadrop trailer comes in at just under 1,000lbs, but a 1,000lb tow rating is just to close, I would rather have a little wiggle room.
