Unusual Color on 1966 Barracuda

To the owners of these Barracudas, check if they all are produced at the LA plant? It might be a special dealer package cars for the west coast.

The one produced May 13 with SO # 40373 and the other one produced May 27 with SO#40500 gives a 127 cars diff. It might have been some 127 cars more than these ones.

Is there anyone who has a Plymouth dealer bullentin from March or April 1966?

This might be interested to solve....!
