I was searching decoding ford window sticker and came across a bit of info. The 1 in the sequence of numbers indicating the build date stands for Job 1. I guess then, later in the year it will become a 2 when minor tweeks are made and Job 2 begins. I think it was here I read that prior to the build it's a 1 and after the car is built it becomes a 2. Job 1, 2, 3... makes more sense to me.
