Police Interceptor Heads?

just got an emails from Mike, he started to go through some papers of his dad and found that his dad worked on a project called the Midnight Express truck in 78 to, I have never heard of it till now. You could not order it from the factory, it was all done by the dealer. He said it was black in color, Midnight Express on the door, and 440 motor (you could get a different motor if you wanted). It was made to sell in the states by dealers where the LRT could not be sold.
