You never know. I worked in Automotive production and we built some vehicles two years in advance. Some were special builds with special serial numbers. Most of those builds were to see were or how every thing would fit into the process of the build with the line workers. Others parts of the plant were to test to see if the Body Shop or Paint Shop processes had to be modified for the new body styles and paints. Sometimes it was to see if the longer vehicle would fit turning corners on the line and not run into some rack or person working on the line. Look deeper into the history of the car. Sometimes it is not all about the money but about enjoying the Hobby. If you can not live with what you have just sell it to someone else and let them enjoy the car. If you think the history is tainted maybe put a modified motor in the car and go racing and have fun.

There are two people that have a lot of information on 1968 and 1969 B Bodies. I will say it Galen Govier he has or had a 1968 Hemi Dodge B Body one of two built, also Furyman on this site has a lot of information on these cars since he owns a lot of 1968 Coronet RT Convertibles.
