Hi Cliff!
-080D is the plant reference code for the F&SO. Basically tells the plant to refer to #80 Special Order for the instructions. At that point of production, there had been 80 special order instructions created. Some may only have 1 car produced, some had many cars produced under that SO.
A twin of your car was found a few years ago, sitting in a field. Undoubtedly ordered by the same dealer.
The - is not related to the stripe.
