Hello NYARTCCFAN,
not really a regular poster here, but I keep reading the forum and listening to the fantastic feeds we all enjoy.
ok, back to the topic, check
http://www.planningchart.de/ and look for the North Atlantic gif and East Coast gif. Maybe that is usefull for you. As lpower pointed, NATs change every day, so maybe you can print this planning chart and plot the track.
regards
