Stop in for a cup of coffee

nice.

so question. What truly defines NOS? I keep seeing this term thrown around. To me, its limited to factory made parts, unopen, unused left over from the era when these cars were new. But lately, Ive been seeing it thrown around in the aftermarket realm a lot more than ever before too. For example, there's several posts on that mopar page on facebook, "NOS Heddman Headers" NOS Edlebrock Performer... etc etc.
