Fender tag

He asked about the
build date

So I stand by my statement above.

Many of us have cars with a Scheduled Production Date (SPD) on the fender tag with a different actual build month on it, either earlier or later. The Mylar door stickers had to show the final production month and year per Federal law.

So until the MDH coding was introduced, there was NO way to know that actual final production day. ;-)
