i have five vw beatles how can i tell what year they were made in.

Ten. Dight if van maybe a number or letter

Sticker in front door jam

The way I was taught, when I was tow-trucking, is look at the tail lamp assembly. As I remember, there is a number under a couple of words. That number is the rough year it was made. Although, we were talking it as truth. Hope this helps.
