:bangJohnZ said:Mikey nailed it - it's dependent on the particular component you're interested in, and at what point that component got a running change, not on the entire car. If a part changed one month into production, then cars built the first month are "early", and all the rest are "late". If a part changed during the last month of production, the first 10-11 months of cars are "early" and those built during the last month are "late". The NCRS Judging Guide for each year car usually has a VIN range for components that had running changes during any given model year.
