It does get confusing because sometimes people refer to "Day 2 parts" on a car and the parts are several years newer. I think the term gets used pretty loosely around here when talking about vintage speed equipment in general. Day 2 is a style of build simply using old non-original parts on a car built with the means and methods of what was popular when the car was new.

I'm with Rick that you have to draw a line on when the old parts become too "modern" or were not available around the time the car was new. I personally feel the line should be drawn a the 2 year mark. So that is my criteria, but if you used it around here- you would still be confused as it clearly has a different meaning to others.
