1965 Dodge Dart Charger

Today I was able to close a great deal.

I have found and bought the screws and the plastic plugs for the license plate front and rear. I was pretty sure that they mounted that on the assembly line before the delivery to the dealer took place.

Today I located these two hot plastic bags! Can these bags mean that the assembly line workers did not mounted the plugs and screws? They just threw in these plastic bags with hub caps and other stuff in the trunk! The work was done by the dealer when they license the car. (Sorry but I do not know exactly how this procedure works over there)!

Any comments or information?
