68-70 Charger Door ID Needed

Can anyone tell by the attached picture what year this driver's-side door is? I know it is a 68-70, but I was told there are differences across those years.

Thanks.

looks like a 69-70 door.....68 lock position is located more towards rear of door.

That's for 69-70.
68 would have the lock knob hole almost at the rear edge of the door.
