May be on the sponsor, don't know. I think it could still be done as is but include "Mopar in a Mopar" into the segement.
In my opinion and mine only, I think the car should at least be Mopar bodied.
IM glad they have it included in the show as it gives you the oppertunity to see many cars you might miss spread among the 10,000 + entries.

There were a number of Mopar bodied cars I saw that do not even participate in "Mopar Country" on the grounds. I saw 2 beautiful Airflow's on the grounds.

Another great event.
