IF the vin is the 5 digit number from the dash plate OR from the frame, then it is the serial number. The only way to absolutely be sure of the delivery date is to have the data plate on the dash with the date stamped on it or other documentation, very unusual, showing the same info.
If you dont have the dash data plate, you can usually get the vin off the frame from 1 of 2 places...use this image as a guide where to look:
With that vin, you can plug it into the VIN registry we have and see what delivery date or dates best fit that number...the list is here:

If you have a vin that is not the factory 5 digit VIN between 10001 and about 36000 then you will need to look at the dash plate and/or frame to find the correct number.
Hope that helps...
Lord send your Holy Ghost into our hearts and make the desire of our hearts Your Will.
