if the Demon still has its original door sticker - it will show when the car was actually completed: MDH (MonthMonth DayDay HourHour)

the engine number, below the head, will show when the engine was assembled

if it was an EXPORT ordered car & delivered NEW "stateside" the VON will be "E3xxxx"

or was it an order originated in Canada?
