Not sure if this will help, but you may need to find the code on the Michigan highway department vehicals back in the late 60's?


Fifty "Bengal" Chargers were special ordered by Cincinnati Dodge dealer Tom Kneer to commemorate the Cincinnati Bengals' first year in the American Football League (AFL). All of the cars were painted "Tiger" orange and had black "Bengal" Stripes, black vinyl tops and black interiors. The cars were optioned with a variety of equipment.

As a devoted football fan, Tom Kneer was very excited to learn that his city would have an AFL expansion team beginning with the 1968 season. He decided to build a special car to celebrate the event. He envisioned mating the sleek new form of the '68 Charger with badgethe feline "Bengal" name and team colors - a match that couldn't miss.

Tom found out from Barry Buse (one of the team owners and a close friend) that the team's primary colors would be orange and black. In 1968, Orange paint was not available as an option on Chrysler Corporation passenger cars, so Tom selected an orange paint currently being used as a fleet color for Dodge trucks. The color he chose was originally developed for use on Michigan State Highway vehicles
